Their "self-hosted" Plausible content is pulled from tics.techdirect.com, which resolves to 46.101.161.209 and shares a reverse DNS with custom.plausible.io. Can't tell who runs the web server on the other end of this, so it may well be self-hosted.
The site also dropped a first-party one-year cookie, and let a third party drop a week-long cookie.
My browser is set to send Do Not Track requests, so my explicit wishes are still being flagrantly ignored.
There is still a lot of third-party tracking going on here, as well as execution of remote code under the control of third parties. It's remains a privacy and security clusterfuck but it's better than it was.
