Apparently they had a falling out or something because there a similar post by the tankie including screenshots and proof that the dude that posted the above is lying.
I don't wanna start my experience by listening to someone else to be honest so I will decide for myself what is better for me.
And up until now lemmy has had a better experience for me than kbin social. Additionally I think kbin isn't open to signups anymore from what people are saying.
I have been using lemmy for more than a week now and have also talked with the dev/admin both regarding communities and on GitHub for a pull request I did. The experience was good and for now I will be staying here.
I also don't like the look of kbin and the ux for now.
I have an account in mastodon, kbin, tildes, raddle and lemmy and out of all, lemmy seemed to work the best for me, for now.
