Genuinely not the reason for me. I've used a Linux distro of one sort or another since 2003 and the reason was the power of the environment. Obviously since I (and hundreds of thousands of others) install popcon I've got no problem with telemetry etc. I didn't actually have any problem with them having the Amazon app in there except that it diminished my ability to do useful stuff, i.e. it wasn't a good product.

I'm not sure combined web/app/site-search is useful to me on a desktop. Desktop search is useful on its own. Web search is useful on its own and site search helps with that but combining doesn't help.

And a standalone thing to access Amazon doesn't really have utility to me.

Because I could easily edit the system to not be painful I stuck to Ubuntu.
