To clarify this a little further: I don't think you can do a sit-in and not expect retaliation. And that's how the labor-managment pushback works. It doesn't mean the labor retaliation won't be justified either - and if Taft-Hartley becomes so neutered that it's no longer sufficient to hold the center, well...

But I generally do think that Google, Apple, etc employees should probably enjoy broadly similar protections to government employees in their private-time expressions. Saying "because you work for bell labs, you can't have opinions" is brutally suppressive of what amounts to today's idle intellectual class. Engineers are almost uniquely in a position to have a think about it all.
