A lot of the shitty seeming useless items are really helpful for people with disabilities, but the people marketing those products never seem to want to advertise to them.

Advertisements which are directed at people with disabilities specifically often don't actually go over that well. People want to buy products that help them, but they don't always want to buy products that make them feel limited by their disability.
I have worked with a woman who refuses to use her walker half the time out of pride. She has fallen and hurt herself many times.
But when the product is marketed as convenient, that just sits in your head differently.

Yeah but still it is unnecessary plastic.

...look around in your household. About 80% of your stuff is unnecessary plastic.

then don't buy it?

As someone who only wants the whites, being able to boil all whites in these would actually be really nice.
