"PMs work for the engineering teams" made me cringe. This statement is no different than what the article is preaching, just another flavor. PMs and Engineering should work together. PMs #1 role and why they should even have a job is bringing customer clarity and urgency. Being a tech-led/product-led organization is just another version of sales-led organization. The ultimate balance is being customer-led which many companies/teams don't fully understand. But I fully agree with the "product CEO take" - as a PM I hate that framing.
