Absolutely! In fact AGPL v3 guarantees that right (otherwise in the US I think arguably the DMCA blocks breaking access protections like that).
In practice, I'm not too worried. It's a fair bit of a hassle, as you'd have to rebuild everything yourself. It'd also require a fork that would make keeping up to date with the main versions new features painful, and it's been moving pretty quickly!
It's only a few dollars a month, if that's expensive enough for you that the time & hassle to fork the whole thing would be worthwhile, email me at tim@httptoolkit.tech and I'll just give you a free subscription.
Yes, you're probably right about the DMCA. Would be a fascinating test case, given the availability of the source under an open license! But of course, will never happen.
I think I more saw it as a challenge to be honest! But if I do get to that point in the future I may take up your generous offer.
Great README docs by the way - spot on in content and delivery!
Morally bad and ultimately self-defeating, but I'm guessing legally fine?
