Honestly Twitch was already fucking up pretty big before the buy out anyway.
I was really soured on Twitch due to there god awful business practices a few years ago and then there really fucked up infrastructure switch earlier this year. Both of the times they just ignored the huge backlash and kept going forward.
Remember Turbo? Remember paying for that to not get ads and to get higher quality streams if the streamer opted for it? Well I remember paying for that and then getting fucked by the paid subs option a few months down the road which did what Turbo used to do and better.
Well gee why would I still pay for turbo if I potentially dont get the option to see Source/High and I still get ads? Oh and if I dont want to get stuck with ads/lower quality I have to sub to each streamer separately. Fun.
When the PS4/XBO came out they switched there video transmission methods to be more "adequate for console streamers and viewers". IIRC the method would send extremely small packets of video of about 1-5 seconds long to "reduce buffering". What happened? Buffering got worse, Skips got higher and it also added at minimum a 40 second delay to every streamer on twitch.
I have a 50mbps down connection. I was completely unable to watch twitch on anything higher then low quality (about sub 240p) and it lasted for months. I couldnt even stream it to VLC anymore using some python scripts. All the while thousands upon thousands of comments piled up on the site bashing the new system and all twitch did was argue with the people begging for a solution. I for one had my posting privileges revoked from the blog just for pointing it out. Seriously it was full on Tethar Atrum ACF. God awful.
The mods involved there ended up getting fired IIRC but the situation was still absolutely awful and they got away with BS after BS because no true competitor exists.
Thankfully they tweaked it (only took them 7 months!) and Twitch is much more watchable for everyone again now but issues are still there like the huge Delay with the streamer.
Dont even get me started with there issues in Europe.
All things considered even if Google royally fucks this up it can only get better.
