Pewdiepie wasn't almost canceled, people tried for years. Most people actually made fun of the attempts. Disney went back on being associated with him. School teachers said his students shouldn't watch pewdiepie. Guess what? Didn't change a thing, he only got bigger and richer from there. His viewers know that he's not a monster, and most people are smart enough to realize that. (and well, the on going theory is that all Brazilians are monsters, so if Gaules is a monster, it is only appropriate for them to only grow more confident on Gaules and dominate the world).
Hundreds of thousands of people even followed the supposed nazifascist that pewdiepie shouted out. That one is still doing well too, by the way. I particularly yearn for his videos, he's just so fun.
Same would go for Gaules. You think that article would do anything to him? It could affect his relations with international brands (probably won't), but he barely has that anyway. Almost 0% chance it would impact how Brazilian companies (ps: he is sponsored by the largest bank in Latin America) see him. Definitely won't impact how his viewers see him, as they probably see the article as petty (it is). And as he said in that 30 minutes long rant, of which 10 minutes were subtitled and made popular, he never depended on "you" to achieve anything, that he even achieved things despite of "you"(international audience, orgs, viewers, etc) working against him. He doesn't need to broadcast the CSGO big events. He hasn't done so this month, and yet he is the most watched streamer in twitch worldwide this month. He has made insignificant events relevant before, and he could do that again. He could make his own event and get basically any interested tier 2~5 teams in it and it would compete with t1 tournaments viewership. He doesn't depend even on the twitch partnership.
tl;dr: no lol are you crazy
