Adding to what you said about interest rates: We’re at the end of a long period of cheap borrowing (very low interest rates) during which overvalued assets were used as collateral to secure loans for investments. These propped-up assets are beginning to drop to their true (intrinsic) values. In other words, speculation and irresponsible practices were propping up a house of cards that’s starting to collapse, and now investors are scrambling to cash in or cut losses wherever they can. So they’re deciding that time has run out for online platforms that promised to grow but still haven’t hit their numbers/monetization goals.

tl;dr: Infinite money glitch got patched (because it was wreaking all sorts of financial havoc) and now investors need to end life-support for risky/unprofitable investments.
