Constructive Criticism and League's direction

So some of the mods are calling for players and league community members to keep things civil and constructive when it comes to criticizing the game or development directions. That's understandable. But it's also very redundant.

Just some small examples of the community being civil:

1. In Season 6, many people, youtubers, streamers, content creators all voiced their discontent over Dynamic Q civilly for as long they could. Riot ignored the community for AN ENTIRE SEASON. That's when people started to personally attack devs and those that pushed Dynamic Q.
2. People have criticized damage creep and mobility creep since Season 5. They kept it civil, and even up to today I see countless examples of people keeping it civil. Champions like Leblanc were nerfed into the ground after being reworked for damage and mobility being too high. Then you released .
3. Champions like Galio or Singed who were buffed then quickly hotfixed for having their respective winrates and banrates rise too much. Then, Twitch was the staple ADC at a steady 52-53% for the entirety of Season 7. People civil asked for reasonable nerfs all throughout that season because there weren't many answers to Twitch coming out from stealth and melting an entire team. Rengar was nerfed and reworked, then continuously nerfed for that same issue and he's a melee character.
4. Players have civilly criticized how cheap and effective ADC/Crit items are, yet many bruisers and assassin items are nerfed because ADCs could take advantage of them. They even tried begin discussions with the problems of AP itemization and the lack of options there as well.
5. Players have also addressed weak towers, first tower gold, the snowbally state of the game, and lack of a comeback factor all very civilly. The new Runes have a glaring lack of defensive focus and heavily rewards getting fed. All issues that we have discussed civilly.

When people have had enough and start to call for developers being fired, you then say to keep things civil. It makes no sense and it's almost an insult to our intelligence. There's very little consistency.

If I am a Doctor or a Lawyer and the people I work for tell me that I'm not good at helping them, I'll eventually lose my job if I improve my service to an acceptable standard.

Hell, I've been in the service industry and the moment the bosses I've had noticed any dips in service quality, every employee was reprimanded and put on watch. If you don't improve and don't respond to the criticism, you get fired.

I'm not sure why exactly Riot developers are above being held to that standard.
