With all due respect to her great writing, I think there’s a mix of revisionist history blended with PR claims going on in this thread. The blog has some good reading, but let’s not get ahead of ourselves in rewriting history around this one person/company.
I can only speak for myself. I worked for a company that is somewhere in the observability space (Sentry) and Charity was a person I looked up to my entire time working on Sentry. Both for how she ran the company, for the design they picked and for the approaches they took. There might be others that have worked on wide events (afterall, Honeycomb is famously inspired by Facebook's scuba), she is for sure the voice that made it popular.
