By all means use Segment. Segment was a great technology with an incredible technical vision for what they wanted to do. I was in conversations in that office on Market far beyond what they ended up doing post-acquisition.

But a company that can't stand on its own isn't a success in my opinion. Similar things can be said about companies that continue to need round after round of funding without an IPO.

My comment is of the "(2018)" variety. Old news that didn't age well like the people jumping on the "Uber: why we switched to MySQL from Postgres" post. (How many people would choose that decision today?)

People tend to divorce the actual results of a lot of these companies from the gripes of the developers of the tech blogs.
