If a support takes CS with ADC or any Carry nearby, it's not good, but at least the same gold goes somewhere. Not letting them take Cannon (or others) is literally throwing gold away.
Don't be that guy.
Same goes to supports with Coin. Don't take CS if other teammates are near.

Im gonna add another PSA here. 
item line does not Magically stop working at 15-20 min. Your Support will still be generating charges. Even if your not the ADC you should let them USE THEIR CHARGES! because they don't make gold with out it and theres no reason to let them run around max stacks. Every second running around with max stacks is wasted cooldown and if your 1 shotting waves or fighting them for cs that your literally going to be given your not helping your team.
@supports. Don't waste stacks on Caster minions unless you have to.
Do you want me to ward efficiently? Let me proc Relic! Do you want me to try to tank efficiently? Let me proc Relic! Do you want sustain? Let me proc Relic! Do you want items to help you not get blown up in 2 seconds? LET ME PROC RELIC!
FYI: Leaving the cannon there for them and pinging it multiple times only to have them take the caster next to it and you miss it all together makes them an asshole. :)
Seriously, if you want the fucking cannon, take the fucking cannon. Making me miss one because of your own ineptitude is not going to incline me to let you take later ones.
There is no ADC that can out dmg a relic shield proc in lane phase. Also ADC's use gold much more efficiently than supports so no.
never trust
please continue to deny your support all cannon minions and try to not let them take melee ones as well.
I thank you for your consideration, -friendly support main
I've started just ignoring the canon because I've given up on trying to go for it but now the ADC's that will let me take it are messing up and losing it.
sigh
This is why I take Minion Dematerializer on supports with Relic Shield. To ensure they can't take the cannon minion away from me.
I don't think people give a damn thought they should it definitely peeves me not only because its a dick move but also because they're practically inhibiting the team from having vision like...I get it you need CS but you're telling me you can't wait one god damn second?
Lol I've seen supports mess it up often enough that I'm going for the cannon as a precaution
If you're using the relic shield right, you'll get the CS
You know what's even worse than that???
Supports that ONLY TAKE THE CASTER MINIONS Like DUDE, if you HIT the CANNON OR MELEE, we BOTH get MUCH more gold! And YOU, as the tank support, get to build your items MUCH faster!
Caster minions are USELESS to hit. Please Supports. Hit the Cannons or at least melee. Only hit casters in mid to late game.
Please.
- An ADC Main who is sick of Supports wasting potential gold income
Problem is that cannon minions are half the battle in all the lanes. It takes a decent amount of thought (particularly if you get bottom role as a fill or secondary) to avoid what is a primary target in both Top and Mid, and even Bottom in most games. On top of that, even Supports make mistakes sometimes, including trying to harass an enemy, killing a minion instead, and losing the Relic charge they planned to have for Cannon. This means an ADC has to micromanage even more on checking how many orbs are floating around their ally.
Not saying it's at all right to knowingly hold your ally from minions, but in normal scenarios, accidents happen. There's a lot going on in bottom in most games.
I kinda feel like the micromanaging is more than it's worth. I feel like it might be beneficial to drop the passive gold income altogether on the Relic line and add a mechanic where it awards gold to make up the difference if a non-cannon is taken (only to the support). There's already a heavy disadvantage to Relic players vs. Spellthief players (or Klepto Ezreals) in that the minion collection creates mandatory vulnerability periods. It would be nice to at least not make it that obvious when those are, and double bonus for also reducing the ADC's burden on reserving key Cannon CS for their supports. I just don't think that's a fun mechanic to work around.
As a backup plan, I don't think it would hurt to make cannons significantly easier to grab for supports lategame, either a much larger HP threshold for instakill, or even a CS stealing mechanic if it's hit with a melee basic attack and an ally deals the killing blow (not a true steal, just make sure both bottom laners get their piece).
if i take it, it's either because i thought they'd miss it/not get to it in time, they're out of charges for relic shield, or i messed up
I hope damage eventually gets so high that supports can no longer proc the relic line to begin with and Riot is forced to rework this god-awful mechanic.
