This is not about community “resistance” to change per se. Or, to the extent that may be true, it is, I would suggest the least important thing.
It is, of course, true to say that some users, myself included, are not especially happy about a change to the default menu following an earlier consultation where it was clear the majority of users did not want such a change. However, changing the default menu would be quite acceptable, to me at least and, I suspect, other users if (a) it is not some Frankenstein amalgam of the traditional menu and Brisk menu, (b) it is not given the name “traditional” and © the traditional menu is presented as a layout option in Mate Tweak with the title of “traditional (gnome-2-like)” layout. Personally, I am ambivalent about"a". But, “b” and “c” are red lines for me. Not for myself, as it happens, since I am an experienced user. But, for the sake of choice of new users.
The resistance that has been encountered is, I would argue, due variously to (a) the proposed changes not being formally notified to users, (b) the mashing of the traditional menu with the brisk menu and © there not being a transparent and easy (for new users) method of choosing the traditional layout in Mate Tweak.
If those things were in place, I suspect there would be support and/or little resistance. Or, at least, I can certainly say that would be the case for me.
But, that is my final word, now, on this issue. I am currently hogging this thread, it seems, and so my opinion may not, in fact, be typical.
If others feel differently they have every right to say so and and I urge them to do so.
