From 2015 on the corporatization took over, the flat hierarchy was completely discarded in favor of multi-tier CwhateverO monster departments, team fragmentation and purposeful reassignments, and basically a 100% annual employee count growth mandate.
That's also around when the big raises and bonuses stopped, and everyone was assigned to a role and level which has a set salary value range etc.
For me 2018 was the end of my patience for it, but I think some are trapped believing in an older version of themselves.
