Read again, I didn't defend anyone. Yes, the work flow and how he has done it over the years is wrong and unforgivable. But you criticised the Remake as a whole, that it would be not necessary even though it is since Tropical Daze should come with the same Art.
Also you mixing some things up. Lewdlab just polish his Game a bit with a bit new content. Cypress Team wants to Remake the whole Game, they want to change everything in Art Style, make some tweakes in the Dialogue and so on.
Again, not defending anyone or pick a side, every side shows the pros and cons. But your argumentation is "Remake = Bullshit" type. It seems you despise the Idea of Remakes in general, at least for me. Like I said, criticising the Dev because of his peculiarity of doing the things he had done is more than ok and correct. But criticising the Remake Idea in general is upsetting.
Here another example with Amity Park, the Idea of Remaking it so it would have more quality and is updated to a new standard is good. But how the Team around G-Zone, Team Bieno, etc. has done it is awful. It doesn't seem like Danny Phantom anymore in the remaked scenes (*cough* the new Paulina for example *cough*). And that's the problem for Amity Park, Paulina is not recognizable anymore without her clothes, the new art is worse than the old, this Remake is bad. As a non parody Game (aka new game from this team), the art style would be good but since it breaks the parody aspect in Amity Park, it's not fitting.
Snow Daze will most likely remain recognizable since even though it has new art, the Characters seems clearly as they should. So why are you "hating" this Remake plan in general. Yes, you can be frustrated about Cypress work flow and how he has make his decisions on how to do it over the years and criticising it. But then to say things like "Remakes are bad and unnecessary" type of comments is a bit harsh.
So yes, remaking this Game is justified. Is it justified of how Cypress has done it over the years? Of course not, these were Bad decisions. These decisions are criticisable yes, but not the general idea of a Remake. How the Remake will be done over the years and when it turned out bad (*cough* Amity Park *cough*) then yes.
