Artificially low interest rate environments lead to a lot of money in the hands of investors, which due to inflation slowly loses purchasing power over time. However, with large reserves, they can easily afford to prop up a business model which persistantly spends more money on bringing "free" features to user while charging very little. Those businesses obviously outcompete any business which do not recieve such investment.
However, as time goes on, those investments must eventually earn a return. Switching from a model which loses money every year to one which must profit every year is invariably going to affect the quality of the product. Especially in an environment where directly charging customers for your service would be a death sentence.
In the absense of such cheap credit, however, a truly competitive environment could potentially emerge, where businesses must be sustanably profitable from the ground up. Esentially this would mean the last 15 or so years has been wasted time in pursuit of this goal, as false monetary signals were steering us in completely the wrong direction.
Some of todays tech companies may survive the transition, but I believe that most will eventually be replaced by completely new ones. Unless we go back to a policy of lowering interest rates to near (or even below) 0%.
