I think I draw the line at the company trying to control what you do when you aren't on the clock. Unless you're in some kind of job where PR is one of the main aspects (like a political spokesperson), I'm not sure it should be their business what you do on Saturday.

Well I think it's also much bigger to be told I can't fall in love and/or find someone attractive just because I work with them. And we can probably agree that office crushes are just as bad if not worse than office romances.

I don't really know, I've never had a thing for any colleague (one exception, really long story, but short version is I found out he's straight before he was ever a colleague, so irrelevant), and I've also never had a job where it wouldn't be allowed. All I was saying is that plenty of "freedoms" are restricted all the time, we just don't word it like that and they don't feel like a big thing.
