There are plenty of fantastic reasons not to, despite the prior issues with Eelco's leadership style. The NixOS Starknet situation[1] was very suspicious and involved many of the wrong incentives for an open source project. One of the primary people involved was trying to get the drops transferred to other people's accounts (getting around geofencing prohibiting US withdrawals too). So it is virtually guaranteed that is being transferred toward something other than the NixOS binary cache despite it being emphasised it would go there. I guess it will be going to "save Nix together" for the fork. All €20 000 or what-not of it.
At least Lix is doing some interesting things with the language and fixing some long-standing regressions, but some of the people involved seem to enjoy standing next to others doing the work whilst they loudly take credit, and participating in cryptocurrency ponzi schemes using open source as the vessel.
Lix claims to have a more welcoming community, but I too often see prominent members gloating about every Nix bugs and implementation details on Mastodon and elsewhere so YMMV.
If you look elsewhere in this thread, many of the bullies are doing PR for Lix and trying to use this situation to their advantage. What no one is disclosing to people is that their fork of nixpkgs (ForkOS) is nearly done, so pointing people to it is going to be almost entirely in their benefit. But, why would sociopaths tell people that when they can just publicly embarrass people instead?
The amount of gaslighting here is frankly astounding. There were some good developers who went over to Lix but also a few pathological liars and primary school bullies. People don't know half of the abuse going on.
Watch out, they may call you the problem when they're accidentally talking about themselves...
It's very bad and one can simply look through the Discourse and GitHub issues from earlier this year to discover the full extent of the problem. Watch how they turn a security issue into PR now, this is just a microcosm of the dishonesty.
At this point, the primary reason to switch to Lix would be if you trusted the Lix folks more than the core Nix team
