Solutions are to either get a better tub, or go on a diet.
Or just live with it until something breaks and causes a flood, which
could lead to more damages to the house. I worked as a did plumber for
years and I never saw a tub flex like you explain, nor did I ever see a
tub with shims or spray foam under it.

I've seen several acrylic tubs installed with high density spray foam
AND shims.

They must be selling some real crap tubs.....
That was unheard of in the past.
There are so many building codes these days, and some of them are darn
near senseless. Yet they allow crappy tubs like that....
Dumb, dumber dumbest....

I'd hate to have to try to repair the drain pipes on one of them, and
even worse, try to replace one of them tubs.

This proves one of the things I always say. OLDER IS BETTER!

Lay a layer of poly on the floor before foaming it, and the tub comes
out like butter.
