It's worse than not worth it, it's defeating some of the main ways they make money.

Misunderstanding this point leads to endless surprise in this topic. No, companies don't just "don't care" for some unfathomable reason. They don't want it in the first place; they begrudgingly make concessions to accessibility due to cultural and regulatory pressure.

The same things that let the disabled people participate, also help regular users escape the very traps and tricks businesses on-line use to make money. Now, supporting the former group may be a rounding error on the balance sheet, but enabling the latter to defeat monetization efforts, not so much.
