That's kind of overstating things, isn't it? Yes, what HP did was balls-up stupid, and I'll think hard before buying anything from them, but companies have liberties too. They have rights to free speech (you don't want the government telling newspapers what to print), and they have rights to sell what they want, just as we have rights to not buy the merde they try to force on us. Twitter has the right to shut down speech on its network that it doesn't like, and that's not a First Amendment issue. Nobody's liberties are being taken away: rather, someone's liberties are being exercised.

Now, I do think that a lawsuit may be in order here, because it seems quite plausible that HP acted deceptively. But that's not "our rights being taken away", which is primarily an issue related to the guys with guns (i.e., the government). This isn't that: rather, it's a company lying to us, and trying to get us to buy their product on false pretenses.
