I think a lot of the commenters here may already have a negative perception of Platform teams. That they are a byproduct of big tech org inflation, a sign that the companies aren't serving their users, etc. The initial hook of "inventing work" then indulges these pre-conceived notions, and you end up with rants on how engineers have lost the plot.
Personally, I found the article well written. Platform teams ultimately want the overall company to succeed. Their leverage - and mandate - is through helping the engineering org ship safer, faster, and more efficiently. The signal recommendations mentioned by the author are spot on from my experience, and I appreciated reading their perspective.
