You'll find that with many sequels and any GOTY titles.
BoTW is massive one, many calling it a AC clone, mad they got rid of dungeons or breakable weapons, empty world etc. or even MGS2, people were triggered with Raiden being the main character and trailers showing Snake to hid the surprise lol That fanbased lived, this one will be alright. I don't know if any sequel can ever work for 100% of that community btw. I personally loved the second game more then the first and love the gameplay changes like going prone, dogs able to smell you and many MGS like features added. So I don't know if its enough to say some shit like "half teh fanbase", we don't have any info to really be like 10 million plus who bought The Last Of Us 1, hate 2 or something like it.
Folks online simply love to exaggerate shit when they are butthurt or triggered etc. Like remember when the fanbase hated EA's Battlefont and it went on to smash all records to become the best selling Star Wars game? Remember when Far Cry 5 was going to flop cause the "fanbase" hated that too and it goes from the fastest selling Far Cry to the best selling Far Cry.
I don't know if I'd pay too much mind to a lot of that you'll always have fans like that, but time will tell how much they really make up of that fanbase
