Big tech has noticed this a long time ago, which is why they hire a legion of "developer advocates", its inorganic in the beginning, but it works long-term and once certain tools get into large companies it's almost impossible to remove.
This is especially true for devtooling companies, and I'd like to see what the 'engineer as a marketer' effect can have on other companies where developers are not the main audience. Any prime examples of this?
A non devtool example I really like is Mercury when I was looking for what bank to use some engineers from Mercury reached out to me letting me know if I ever need help or run into bugs to let them know
