Sure, why not? It's not like it's a huge sacrifice on my part. It's just a little reduction in convenience. No big deal.

That's not the issue for me at all. The issue is if sites require me to use specific browsers, to not use specific extensions, to not be able to modify the browsers, or to adhere to specific requirements in terms of the OS I'm using. Having to maintain a completely different environment in order to use certain websites really is a loss of convenience that I object to.
Don't get me wrong -- I don't see this as a huge moral issue. Sites can do what they want, and if I don't like what they want, I don't have to use them. Opting not to use them strikes me as a reasonable and proportional response.
The only thing that makes me a little sad is that it's just another thing that makes the web worse and less useful.
