Riot has allowed Sinatraa to come back to competitive play so I don't quite understand why you're blaming them? After the allegations came out I think Riot acted in a way any E-Sports division would, you suspend the player until you complete an investigation? Riot is a company at the end of the day dude any company would literally act in the same way...
In terms of the G2 stuff, I'm pretty sure that was purely a PR move by Riot, again, They're a business and do you think it would be good idea to partner a business who's currently in the spotlight with their CEO/Owner being suspended for 8 weeks no pay? No it looks like a horrible PR move...
XSET missing out on Franchising was a puzzling one to me, didn't really make much sense but im sure Riot has their reasons. As to OPTIC, like i've said to others, OPTIC doesn't have good track record in franchised leagues and with all the behind the scenes drama going on with OPTIC, plus the fact that OPTIC has never done anything for Valorant apart from having a roster due to the Envy merger it would just be stupid to go with them. Riot stated they wanted to partner with teams who were dedicated to the scene and who were willing to give back to the scene and build it with them. OPTIC hasn't done anything like that so far.
