Heroku (YC W08) was acquired by Salesforce all the way back in 2010 [0], a little over 15 years ago. A lot of people forget that, and assume the acquisition was somewhat recent.
Pretty illuminating reading the thread from 2010, it was big news at the time.
Salesforce mostly left Heroku to do its own thing for a long time. Since that changed, dumpster fire.
This is surprising to me. I actively used Heroku during the early to mid 2010s. I do not remember ever seeing the Salesforce logo there much later.
