Open source may have eaten the other end of the market. Lichess is good: not as feature rich as Chessbase and a less complete database, last time I checked, but less buggy and faster for some purposes.
It's hard to imagine a competitor at say $50 that did say 80% of Chessbase's functionality would sell many copies. It needs to be 150% of Chessbase and cost $200.
Scid (and forks) also exists in the open source world. It works just fine but the UX is lacking; I've never met a serious player who relied on it. It's the GIMP to Chessbase's Photoshop. So the UI needs to be great or to be a clone of Chessbase's.
There's also Chessbase mobile which was an amazing product when it first came out. It has the three features people really want from Chessbase: search for a position, search for a player's games, run engine analysis. All in the cloud. For something like $6.99. Sadly Chessbase seem to underprovision servers for it and Android nerfed it by preventing you plugging in strong OS engines. But it's a sign they can give away the product if they need to get into a price war.
