rather worried that it's going to go the same fate as ShareDrop (https://github.com/ShareDropio/sharedrop) and Snapdrop (https://github.com/SnapDrop/snapdrop) where they recently got taken over by LimeWire the crypto/AI company.
and it has people building alt.clients

(though these are not webapps, which was your main shtick i'm sure)When I discovered that it now uploads stuff to Limewire I was so annoyed that I had to admit I suggested a harmful tool for sharing private data. So much, that I will never recommend a similar website. Either I'll host it my self or suggest an installed tool through F-droid, if it exists.
I mean, it is entirely my fault. I knew the security risk, but set it aside, because I didn't think some known guy developing an open source tool would in his name try to grab your data.
