I think it's less that we're expected to sympathize, and more just that they've realized enough people will tolerate it. With OP's example, Taco Bell has clearly decided that whatever business they may lose due to people deciding to not go to Taco Bell anymore because of the lack of napkins will be less than whatever they save by not stocking napkins anymore.
And they're right.
Don't get me wrong, it's a shitty thing to do, but between people in general not realizing that this place doesn't even have napkins anymore, and people deciding they still want semi-delicious garbage tacos anyway, they're really not going to see a big dip in revenue. They've simply realized that they really can just make their presented experience a little shittier just to save some money.
