We do waterfall still. We just call it agile because there are scrums and standups.

Honestly hard to say. Very much have respect for existing ubiquitous tools and for their copyleft and open source advocacy but they come across as very ‘elitist’ and reluctant to move to more common open source patterns (for better or worse).
