Must be on one of those lists, because my pi-hole blocks it too. It's funny, just yesterday I was searching around for some server log analytics solutions for my site (settled on GoAccess for now) and they kept popping up in my search results. Never clicked on them though as the link descriptions made it clear they weren't what I was looking for.
The title is a bit misleading IMO. The company was in a state of flux before they pivoted and rebranded as Segment as far as I can read (when they had a different name). The actual company 'Segment' seems to have been on a great course of growth since then.
Surprised to see that mparticle isn’t listed as a competitor. I’ve seen what Salesforce is working on in this space and it’s nothing compared to mparticle and segment.
This is an all-too-common story with startups, as PG points out in several essays. Often startups only make sense looking back, and don't lend themselves to business-plans & analytics.
I note that the uMatrix web browser add-on blocks the entire domain of the company.
