No, he was not. That's the point. People don't know how to read, misinterpret Riot's posts, and make it say what they want.
VEIGAR was never promised compensations. They didn't want to do a total nerf to Veigar (which they definitively did not do), but Veigar was never promised anything close to compensation in any post made by any Rioter in any fashion regarding DFG's removal. The only posts where they even talked about Veigar or compensation were the patch notes, Riot Jag's 5.2 patch forecast, and a post by Scarizard and in none of these cases did they promise compensation for Veigar.
It. Did not. Happen.
People just skipped the 5th grade and forgot how to read plain English, and decided that because Veigar was mentioned as a user of DFG, that meant he was in line for compensation for it's removal alongside the champions who were outright designed with DFG in mind and did not function without it.
He was not. This is fact. Veigar mains can pretend all they want but they're both putting words in Riot's mouth so they can blame the company, and lying to themselves to feel justified in their vitriol. In fact, they very plainly stated that Veigar was not going to be straight buffed. As in the exact quote from Meddler following DFG's removal was
"Odds are very high Veigar won't just be straight buffed. His kit's got some serious counterplay issues (undodgeable instant stun when used right, two point and click nukes) that we need to address."
Not only did they not promise "compensation" for the removal of DFG, they were very clear that he was not getting buffed to compensate for it. They promised to give attention to Veigar, which they did, they did not promise to "compensate" him.
Like I said, I'm not saying he couldn't use some work. I'm just saying all the Veigar players need to stop plugging their ears and blindly following a stupid rumor of words that were not said and raging every time someone comes around and says "for the love of god that wasn't what they said".
Here's the thread with Meddler's post: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/XQ50JbAz-53-is-almost-here-and-none-of-the-promised-champ-changes-are-on-the-pbe?comment=000700020000
and here's the Reddit post of Scarizard's: http://www.reddit.com/r/leagueoflegends/comments/2scgcq/deathfire_grasp_to_be_removed_in_patch_52/cnoaup0
Now, if angry Veigar mains wanna insist on warping Riot's words to mean what you want them to mean after reading the actual Riot posts the rumor came from, feel free. But you're outright wrong if you're "interpreting" anything they've said to mean Veigar was getting "compensated". That's just simple fact. It's not what they said. At all. Period. Whatsoever.
Please, enlighten yourselves and stop spreading this stupid rumor on the boards again: Veigar was a no-counterplay load of bull before, and DFG accentuated that playstyle. He isn't that any more. He's too weak, sure, but considering Veigar players were outright told the opposite of what they seem to think Riot told them, I'd shut up with the whole "WOW RITO U GUYZ R LIARS" crap, and maybe focus on an actually worthwile attempt at communication. They're going to (rightly) avoid you guys as long as you refuse to do anything but live in a fantasy-land where Riot says whatever you want to hear.
Ya'll can downvote reality all you want, but you're just making yourselves look like illiterate idiots, and it's not going to change what the facts are.
