signal is a good option for messaging. it is technically american, but i feel like FOSS projects should generally get a pass.
also, as an american who is very not okay with what our (russia's) government (puppet) is doing, wouldn't supporting non-american businesses mean paying the tariffs and supporting the oligarchs? i'm not really sure what us yanks can do besides just trying not to spend ANY money.
i mean. wouldnt rebadging it and putting a "fuck elon" bumper sticker be more of a message than selling it to another sucker?
(also ripping out the spyware laden computer system that reports all activity INCLUDING CAMERAS back to hitlerHQ and can remotely disable your car)
