There's a really odd moment in that video where a woman talks about the death of Pride, how it's no longer and revolutionary thing, and well, I'm wondering what it is she wants. As far as I'm aware, we have equal rights for homosexuals as heterosexuals. If you want to get married, adopt kids, you can. Gay marriage means you get all the same benefits as straight marriage. We take this as far as telling private businesses that they can't discriminate, and there's no doubt that you'll get prosecuted for not doing so. The war was won completely and at that point, it's time to put the weapons down and get on with something else.
As for the "corporate sell-out" angle. This chart tells you everything.
Back in the 80s, when most people thought that gay sex was "always wrong", of course companies weren't interested. When most people share the view I've always held, that 2 consenting adults can do what they like to each other, and homophobia is very much out of favour, of course companies are going to join in with that.
