I think that ppl are seeing only the bad side of day 1 patches, because of that I would like to point out that, while companies are idd guilty of releasing buggy products, it wasn't that uncommon in the past either, FFVI had a critical bug in the evasion stat (aka it didn't work) that could've been fixed with a patch.
The witcher 3 was a huge success, but part of that success is also earned by the dev team releasing quickly fixes after launch since, there were several problems on different systems.
In my opinion, post launch support is much more important nowadays because of this and we should be very mindful of that. Or we'll get more WB shenanigans that tells us that they are too busy with DLCs than working tpo fix bugs
