The purpose of regulation should be to combat harmful business practices and not to try to destroy a company that grows too big for the tastes of EU politicians. Does Booking.com use their size to harm competitors in any harmful way? Not that I know. Do they abuse their customers or accommodation partners? Not that I know. Regulators should show some evidence before making hostile moves, it seems they are just acting on ideology and not in the interests of the customer. But EU rulers and their worshippers among the population do live in a kind of fantasy land of 300 page PDFs, while ignoring very tangible problems.

Booking.com should of course have to make good on any promises or deals they make with guests and with hotels, which they seem to do.

If there's one thing that regulators should take a look at, it is the practice of selling non-refundable hotel nights. Booking.com does it together with hotels who able such offers and the whole industry does it at a limited scale, and have always done it. But the way I see it, there is no reason that a hotel shouldn't be able to always refund any room if it is cancelled at least one month before the stay. You should always be able to find another occupant for the room within one month. The only reason hotels sell non-refundable rooms is with the hope of double dipping when somebody has mistakenly reserved it without paying notice that it was non-refundable. I can see no argument against mandating a one month free cancellation for all hotel bookings on land.

No, that's not what I'm saying. Just because I clarify my position doesn't meant that I'm asking you to believe me or trust it.
