Tech companies and their executives have, broadly, moved to align themselves with investors and adopted a posture of, often, disdain or outright hostility towards their users and employees. If tech companies don't value you, why provide value to them? If they back political positions hostile to your interests, why not return that hostility?
I like localsend more than kde connect. I like to play around with different Roms on old android phones and would install kde connect every time I wanted to send screenshots and it would enable by default all permissions which I didn’t want except for file sharing
Oh and localsend is written in flutter which is going to (hopefully) become better because canonical is gonna help improve the Linux side of things
