In an ideal world that's true, but in reality it's probably not a good approach to treat political alliances on issues as independent transactions to be taken at purely face value. If you're an advocate for free speech, it's probably worth being extremely dubious of Republican efforts aimed at "big tech" even if they claim to care about the same issue you do. For one thing, those efforts are clearly motivated by very specific speech and even if you hope that translates into better protection for speech in general, it's worth considering if that's actually what your new allies are actually aiming for. There's a long history of policies claiming to be for the general good ending up exclusively benefiting a select few in practice. That's not always the case of course, but especially worth keeping an eye out for when the folks advocating for the policy are making it fairly clear up front that's their agenda.
The other issue is a bit more strategic. Policy victory brings electoral victory, and you don't get to pick and choose which other policies come along for the ride when someone wins. Nobody agrees with a politician or political party on every issues of course, but it's probably not a good idea to ignore the rest of their views entirely just because they happen to back at least one policy you agree with. At the risk of invoking Goodwin, if you weren't a fan of that Hitler fellow but supported him anyways because you liked road construction, you might have regretted your choice.
