How can I opt out from this and future feature previews?

I do not expect that my request/feedback would matter at all[0]

I am not interested in getting notifications about such testing.

How can I opt out of feature previews?

[0] there are multiple reasons for that claim:

  • note size of Microsoft and amount of feedback
  • my already given feedback was ignored in the past
  • in many cases where I would want change something my interest and Microsoft interest would be competing anyway, and I am not naive enough that Microsoft in such case would care what user wants
