It won't work.It would be interesting if people organized a Hulu blackout day when nobody used the service in order to show support for it remaining free.
Back in July, when YouTube announced the forced Beta Channel switch, there was a blackout from July 10 to 15. When we came back, it turned out YT delayed the switch, and it just happened earlier this month.
If it didn't work for YT, it's not going to work for Hulu. After, roughly 600,000 people protested the Beta switch on YouTube, and 98% of the feedback on the switch was negative, but they did it anyway. They don't care about us. It's obviously the same with Hulu.
