If you plan on shitting on a company, or a game, or anything for that matter, use OBJECTIVE points. E.G. "THIS SUCKS!" is opinion at best. "X game feature ruins flow because Y", or "X plothole makes no sense".
You claim FF13 made no sense, but it did. The only problem with it in regards to following the rules it sets out is when everyone becomes L'cie, but then turns back for no good reason. BUT, you claim Square is diminishing in quality, while stupid crap was in their stories since the beginning. Remember the good old "it was actually aliens on the moon the whole time, here, take this spaceship" moment in ff4?
KH is just bitched about people because it's spread over multiple systems, so it's hard to play all the games, but the story is pretty well written, and the gameplay is fun for the most part. Yeah, 358/2 days is repetitive. But abysmal? Whaddafuck you talking about? Go play an actually bad game, because this ain't one. Repetitive is all, and that turned some off.
If you think FF7 got ruined by other games you're flat out wrong. Firstly, ff7 is the same game. If other things existence alone bothers you, then you have some problems beside game quality. Secondly, Crisis core is pretty damn good (though i understand some didn't enjoy the combat) and true to FF7. In fact the only thing that's retconned if i'm correct is that zack gets killed by more than 3 soldiers this time. But really, how anticlimactic would it be if that was the end of the game? And "cloud had to overcome stuff"? Did you even play crisis core? There's quite a few emotional barriers for zack along the way. Can't comment on dirge as i've yet to find a copy of it, though gameplay looks meh from what i've seen.
13-2s sequel was made with fan feedback in mind and fixed pretty much every problem with 13 gameplay wise. Better combat, better leveling, less linearity, more side missions. The fact that they kind of retconned the end of 13 is kinda iffy, but i'd say this game is a good example of how to do a sequel. Keep the good parts of the original (art direction, interesting combat in theory etc) and improve or remove what was bad or didn't work in tandem with the rest of the game. It also had a pretty good story IMO, with my favourite villain so far.
13-3. Well, not much to say. Not out yet. But i will say, just because there was a ton of bitchy people regarding the other games doesn't mean there is no demand, and like i said above, SE showed how they can do a sequel to a main game, after the mess (albeit a mess with fun combat) that was X-2. Go to a soundtrack video on youtube for 13 or 13-2 and see what i mean from the comments. The game has it's fans, they just aren't loud.
And XIV? (I assume when you said IV you meant it because it sounded MMOey how you spoke about it). They made a game. It was bad. Fans didn't like it. What would another company do? Go F2P and see how much money they can squeeze from this shitty project. What did SE do? They remade the game from the ground up in order to make their fans happy, and from what i can see (Haven't played the game yet, but have watched some streams and reviews) fans fucking love the new version, as do reviewers. That is just flat out something good to do. They even apologised countless times, and one of the devs i recall being quoted as wanting to bring honour back to the FF game with the relaunch. That is not something to hate a company over. Not in todays world where being a loyal customer and buying new rewards you with buggy unpatched games complete with a long ass code for disc locked content.
You say you don't want to hate this company, but what your saying can be charitably described as opinion, and uncharitably described as moronic drivel. It's just "this sucks, that sucks". No reason behind it. Now, SE isn't the greatest company ever, but what they are is one of the very few AAA devs who has shown that they still care about quality more than money, and has made countless games i've enjoyed, even if they made some games i didn't. And that much should be respected.
