Careful there - Microsoft and Canonical are increasingly cultivating a very close relationship that includes lucrative data sharing. There was a scary story on HN seven months ago, 'I saw that you spun up an Ubuntu image in Azure':

Canonical knows everything an Ubuntu install at your IP address installs with "apt get" unless you change your repos to a mirror that you know for a fact doesn't share its logs with Canonical. And Canonical is pushing the Snap Store that it alone owns and controls, and which it can Big Brother monitor what every single IP addr installs.

So Canonical doesn't need closed source spyware to make money spying on you.

For the most part though, Canonical seems it will only use its spy data to market products developers are actually potentially interested in. If you download a bunch of container tools Canonical may wish to market to you that a certain service they make money from might work for your needs. And all things considered it actually might.

I do use Ubuntu btw, mostly in WSL though. I will go back to native Ubuntu though once all the art and music tools I need run as well on native Ubuntu as they do on Windows, and once Ubuntu is as hassle free on laptops as Windows is. I recently bricked a native Ubuntu install because I forgot to turn off secure boot, which somehow broke the proprietary nVidia drivers I need.

EDIT: Canonical seems to have closed down its Ubuntu One cloud storage product... I thought Canonical was still trying to offer an alternative to AWS/IBM/Google/Azure but it seems they are just focusing on their OS now. Someone correct me if I'm wrong.
