I love the article, and love the genuinely appropriate intellectual outrage, but isn't this just the market telling AutoDesk that it was paying too much for its enterprise sales function, and that it should be able to run sales more efficiently ($375/seat cost of sales rather than $500/seat cost of sales), when the sale is happening at the enterprise scale where lots of seats are involved?
Given that your largest customers are generally your most profitable, the market was simply telling AutoDesk at the time that it was spending more than its peers selling to large enterprises and matching per-seat SMB sales costs shouldn't be their benchmark for enterprise sales costs.
By shifting the target from $500 to $375/seat cost of sales, AutoDesk would have kept their margins but doubled their returns. Alternatively, AutoDesk could keep the cost of sales unchanged ($500) and bump up the enterprise price from $1,000 to a little over $1,125, and achieve the same goal. The market doesn't care which approach AutoDesk takes, but it knows the company was giving away too much margin on enterprise sales. Most modern SaaS companies today take the later approach, except they would charge enterprises $2,500/seat instead of a little over $1,125/seat.
AutoDesk has had some very forward thinking senior leadership at different points in its history, but it's also made some missteps. Writing a wonderful assault on the accounting industry instead of realizing that enterprises will pay $2,500 for the same thing SMB's are buying for $1,000 is an example of one of those missteps (and yes, AutoDesk eventually figured how to screw over customers with pricing, but that's another misstep, explaining why I no longer own any AutoDesk products).
