I believe that most software license agreements go beyond the grant of power that constitutional copyright gave to the developer of the software.
IOW, much of what is in EULAs should be unenforceable. We’ve already made a little progress on that, with some of the worst EULA terms out there being stricken, but we have a long way to go.
And if you truly believe in EULAs, try benchmarking some software and exercising your right to free speech by publishing those benchmarks on your own terms. That’s a violation of quite a few EULAs out there.
What I know about them personally, is that I’ve never had one of them get in the way of what I was going to do as a consumer.
I’ve read about others having problems, having to do with various things that they want to do, but I’ve just never had a problem with them. Maybe I just don’t do too much with my software, or whatever it is, that causes me, as a user to not have problems with them, I just don’t know... :-)
