Yes I absolutely do agree with that.

Designers and product managers may completely ignore people like me, trample all over our needs and ignore us. Why would they care about the one percent. All good luck power to them and their values.

But I am also not the least bit concerned with whether their products are a success or not. Why would I care if they do not?

Yet I cannot concur that "almost every" site does. No, there are some that do. Moreover, those sites seem to self curate as being of very good quality. So I am happy that there are thoughtful, intelligent people out there who "get it". When they stop, so do I, and just move on. It's not personal and I'm not invested in them.
