Cities: Skylines 2 devs warn players of performance problems: 'we have not achieved the benchmark we targeted' - sh.itjust.works

I’m more concerned with the fact that they’re not supporting the steam workshop and using their own mod platform
Why is that concerning? I found the reasoning for having their own platform convincing.
Not OP but I have 0 faith in companies to not pull the plug when they decide something isn’t making them enough money. Just look at all the old games online games that have been rendered near useless thanks to the company that made it deciding that it’s not profitable to support anymore. Sure, the same could happen to steam workshop too, but I have more faith that the steam workshop will be around in a decade than whatever proprietary knockoff paradox is using for CS II
Steam Workshop is several years broken for Cities in Motion 2 without any changes in Cities in Motion 2
