I think you are being ridiculously harsh.
Hobby Link’s kits fit well, but because 3D printing is more rigid than styrene, it’s harder to correct warping. I disagree with your assessment that the resin can’t be fixed. I have done it, with boiling water (10 seconds in). Hair dryers are also considered an option.
We have been putting up with warping in styrene kits for decades (the hull for the Dragon M1A1 Abrams is notorious for its fit issues). 3D resin printing is a newer form. But to expect a small manufacturer to wait until all possibility of warpage is past, or to replace everything that might go wrong is, in my world, asking so much these small shops will soon go out of business. I’d rather have the kits (which you aren’t going to buy anyway by your own statement), than wait for styrene manufacturers who may or may not come around.
