Exactly. I think an aftermarket VESA mount is pretty much required these days for modern TVs, that’s the bad news. The good news is that there are plenty of options (center base, wall, swivel, etc), some very affordable, and they should last for multiple TV generations (check VESA pattern, weight limits).
But I get that these tiny, wide feet can be mind boggling at first, since TVs all used to have center stands for decades. Finally, TVs got too large, the cost savings and stability from two tiny feet won out over the alternative of the large, heavy single center base.
