The reason is that Squeenix has been gradually tarnishing FF over almost the last 2 decades, and FF7 Rebirth is a reflection of this.
The original FF7 was a gold standard of time. It was quite literally revolutionary, it was new and interesting, it pushed gaming forward in a technical sense, as well as the entire RPG genre in terms of popularity. Square Enix took a very expensive and significant creative risk in making FF7 and they succeeded.
After FF7 they got out a few more games people liked a lot before the decline (Anything after 10/10-2 has a significant amount of people to criticize it), but they wanted to change things around too much without realizing how much of their audience they alienate in the process. They don't give a lot of people what they wanted and the series has felt disconnected from a core, reliable audience.
Mainline FF games had much longer stretches between them, and the reception was poorer with each release. FF11 was an MMO, which is a fundamentally different audience due to its genre, and while it could theoretically exist in parallel with traditional FF mainline, it had issues.
FF12 was indicative of the decline but wasn't outright hated.
FF13 (aka the Lightning trilogy) ended up taking 4 years to complete, and their reward was a mixed reception, falling sales and a newly large group of people to criticize FF as going downhill.
FFXIV was another MMO that was half-baked and people hated it upon release, not to mention it was yet another
In essence, there hasn't been an FF game that was liked without a significant amount of detractors since X, which was 2 fucking decades ago.
FFXV was a bloated and empty open world ARPG with a disappointing story and cast.
FFXVI was the same as above, just on a failed console.
FF7R is an episodic remake of 7 which changes the game's iconic combat system to the ARPG shit, on top of many changes that weren't favorably received and tries to coast off its budget. It simultaneously takes no risk, changes shit for bad reasons, and drops the ball.
Pretty much none of these, besides the slow repair of XIV, have given them much goodwill in the FF fan's eyes, let alone the average customer's.
The first 11 mainline FFs (I through X-2) came out over 16 years. The last 8-9 mainline FF games came out over 21 years, with all the aforementioned problems and issues that come with those.
Exclusivity is only a small part of it. People would buy shit like Mario and Pokemon games in a heartbeat on Steam, and Bloodborne on PC has been a meme for a long time.
It's just that FF7 Rebirth wasn't something that a lot of people wanted, at least in the way they did it.
