They are not now, and never have been, and engineering focused company. The creation of the Salesforce platform itself is (or was) based entirely on Oracle tech...and it was SOLD extremely well because it solved business problems.
Salesforce has failed to innovate outside of releasing the CRM as a SaaS product back in 1999...which is why they have bought innovation, and then integrated it poorly...see Heroku, Slack, Mulesoft, Tableau, Quip, Demandware, ExactTarget, etc.

I worked there for a short bit. Most frustrating experience of my career. It was the epitome of rest and vest well before COVID.
Extreme lack of urgency, little attention to quality, and a huge focus on sales and marketing.
Salesforce will print money for a few more years until someone makes a less awful CRM solution and just crushes their business...so long as Salesforce can't buy that company, integrate it badly, and disillusion all the employees that made it great.
