The answer to your question is in the line you're already quoting: whether you like them or not shouldn't make a difference. My point is that its bad form to use strong words like shady, unethical, disgusting and "fucking disgrace" this lightly. I'd reserve those for situations where you have a clear reason to believe customers are being purposely misled with (bordering on) criminal intent, which is clearly not the case here. This is rude and doesn't help in regard to fixing the issue (assuming there is one), nor does it facilitate reasonable discussion about the matter.

Could they display their fee more prominently? Sure. Should they? Maybe, but it's not like they are hiding it either. Additional fees that aren't included in the quoted price are pretty common in the travel business, so I'd call their fee structure relatively simple and transparent. Are you going to call budget air travel companies unethical for charging an additional baggage fee, too?

It is a reasonable expectation to be charged a commission by a site like AirBnb. I'm happy with the fact that they display the commission before ordering anything or even starting the order process. I'm also glad that they transparently charge it to the end-user, instead of making it a hidden fee by increasing the price.
