While I don't pretend to have been party to internal FB conversations when certain decisions were made, as an advertiser, FB has definitely done some things to significantly erode that trust over the years.
For starters, encouraging advertisers to spend money to build up an audience with the assumption they could continue reaching that audience much like email, only to throttle organic reach to zero was pretty bad.
There have been other things such as being extremely...generous...with the definitions of how some ad metrics are defined and what defaults are presented. Even as an experienced advertiser who knows to look for those things, the lengths to which some of it it is buried is astounding to the point of it being hard to trust that it wasn't intentional. And the recent lawsuits around such things shows I'm not alone in that feeling.
