I said my own opinion, I think it affects this situation only in epic games.I think the issue is more due to the fact that there are not many high-profile AAA releases this year compared to years prior. It seems the industry has gone back to releasing everything during the Christmas season instead of spreading it out over the year. The uncertainty in the current market situation is probably why they did so.
Epic Games Store is only 15% of the PC game market. PC gaming accounts for 19.5% of the total video gaming market, meaning Epic's "disruptions" accounts for only 2.9% of the total global gaming market. To think that Epic giving away old games in exchange for your data causing overall sales to decline is laughable.
