They'd have to pay developers money to work on CoH2. This money has to come from somewhere.
Their previous publisher, THQ, filed for bankruptcy because they didn't have enough money, so it's a very real thing that is important.
They had all the resources since the SEGA takeover to make sure the game was optimised and basic bugs and crashes wouldn't plague its community for months, sometimes years. It's not just a new thing that has become a problem now when money is not flowing to them like it did in the early phases -- it's something that stained their work on CoH2 from the very beginning.
Their priority on microtransactions and DLCs is fine if that money is used to make sure the game's basic functionality is problem-free, but not if it only serves the profit interest while the players are left shafted. I can speak for myself that I've purchased about 70% of all skins and other items from the in-game store as well as about 10 commanders for various factions -- the game is still performing like they never received that money from players like me.
And it's not just memory leaks, overall performance and bugsplats but also things like War Spoils rework that took half a century, balance patches that fixed one thing while wrecking fifty other units/abilities, releasing new factions in ridiculously OP states, etc. It's just a basic case of incompetent work, hence the "Lelic" reputation they have.
