This is season one 2020? There are almost 500 episodes right now with other uploads mirrored here (unfetched) at 373 episodes. Three years later... what is the point of you doing this?

Whats more puzzling is why this bothers and upsets you so much?

Maybe the OP enjoys and wanted to try to interest others. I personally have zero interest in the Chinese cgi shows. I do watch some of their animated series occasionally.
The first time I watched One Piece I think it was the beginning of season 6 In dubbed on Adult swim Saturday anime night on Cartoon Network somewhere between 2007-2010. There wasn't a lot of anime available online back then.

Anyway the point is maybe someone will watch an episode of this show and if they like it make an effort to find the whole series. If not they move one. If I did have interest Id check out a few of these available episodes to see if I did like it before bothering to move mountains to acquire the entire series.

Maybe it bothers the first commenter because that person is downloading and watching the series but now is getting further behind in the episodes. Having over 500 episodes and then going from 373 back to 10 seems to be a big disappointment for that person... it would be for me too.
Maybe these are better versions since the other uploads have not been fetched here but there will be a long wait to catch up.

But I do understand your frustration of seeing redos of certain anime seasons over and over or uploaders never finishing a series.
