I pay for things I could steal as well, because I like to support those companies. However what we have here is an entire industry working towards setting up their offerings as a worse product than free. Not just more expensive than free, but an objectively worse product, and they've acommplished this in part by eroding consumer rights.
You might expect some people to take an extremely principled stance but it would be unreasonable to expect the majority of society to do so when the companies themselves are operating as unprincipled entities.
