uTorrent sold out, its decline is not only due to BitTorrent becoming less popular, but also because what was once a very thin client at one point was bundled with malware so a lot of people kept using old versions or switched to clients like qBitTorrent

While discord doesn’t necessarily cost money, it for sure also isn’t free. In fact it’s the reddit problem but way worse. A proprietary non-searchable database with all content fully licensed to discord including the right to sub-license. At least, Reddit had an API and is still searchable through their public facing http. I mean I get people don’t want their group messages readable by everyone, bit for large groups, it makes sense.
