To people only focused on short term dollars, perhaps. But what impact will it have? Certainly an impact on productivity in short term, perhaps longer? Are there equivalent replacements for all the slack hooks people have in place now? How long will it take to become 'just as' productive in Teams? 1 month? 3 months?

$35k... that's... under $500k/year in licensing they're paying? Will they take more than a $500k hit in productivity?

By HN standards, $500k isn't even the loaded cost of one intern these days in SV, but... even in the 'normal' western business world... $500k/year is likely the cost of 2-3 engineering staff. Trying to eke that much savings in the short term seems short sighted.
