I feel the moderators should have been informed about this prior to changing the logo (before official announcement in meta). I hope they were informed.
With this update came a request from Canonical to update the banner logo as well as the trademark copy in the footer of the page.
While it's normal for companies to ask for changing their logos where old logos are used, Stack Exchange should have thought about this in a different manner when Canonical approached them.
This could have been the perfect time for a new logo for our site, which could have been created by the Ask Ubuntu community, and maybe even a site redesign. I know that site redesign is quite a time-consuming process, but letting the users choose a new logo would have been a better choice.
And this kinda reminds me of my old question. For how long is the Canonical sponsorship gonna have strings attached? Now let's say the community decides to change the logo, there was a logo competition organised in meta, and a logo has many upvotes, will the highly upvoted logo be considered as the new logo by Stack Exchange? Or does it require authorisation from Canonical?
I think it's time we rethink about the sponsorship such that AU can be more independent IMO.
