It did not.

Booking.com did that.

I do however always choose an apartment for corporate trips, but always via booking.com.

This is sort of a funny argument. I promise that AirBNB prices have no impact or influence on hotel prices. It is generally the opposite, AirBnB rates are often influenced by the prices of surrounding hotels.

The number of travelers staying at an Airbnb versus a hotel is under 1%. This is clear by looking at overall inventory available. Even a decent market _might_ have 100 AirBnB listings, that same market will have several thousands (possible 10,000+) of hotel rooms.

Generally the opposite is true. AirBnb hosts will justify their nightly rate based on comparable hotels in the area. But the average Marriot for example isn't all that worried about the handful of AirBnbs nearby that they might be losing customers to.

That depends on the place. Where I live the near touristic destinations have poor tourism infrastructure so AirBnB and similar is thriving there.
