Again, the problem is that Fairphone provided and still provides this support for the Fairphone 2 (albeit not from the start, it took some months back then), so there’s precedence.
That’s the standard the Fairphone 3 is now measured against in this regard.
That users do that seems understandable enough to me, I just don’t get the impatience and undertones of alleging some kind of ill will on Fairphone’s side.
