> my concern is convergence computing will reduce the importance of desktop interfaces and the freedom we have to install whatever applications we want

Yep, it absolutely will I expect. All the pieces are being or have been laid to build the new world where only a "trusted" device will be able to use the internet. Us nerds can still have our Linux, but it won't work with much of the internet because we won't be able to pass attestation.

Building to that future is exactly what I would expect from Apple, but Google doing so has surprised me. Google doing so is also the thing that will bring it to pass, so there's a special seed of hatred for them germinating in my heart right now. Hopefully I'm just being alarmist and paranoid, but I really don't think I am.

I think tech companies are realizing that the biggest "mistake" they have ever made was giving so much freedom to the desktop user. They hate that we can look into, modify, and delete files, hate that we can add custom-made software, and hate that we can identify and turn off tracking/telemetry. They realized this with the mobile platform and locked everything down, but by that time it was already too late.

If this trend continues, then self-hosting may become the final bastion of hobbyist FOSS.
