I suspect the industry's culture of job-hopping doesn't help accountability either.

Facebook kicked off a bunch of 'metaverse' projects in 2020 (even literally renaming the company) and 5 years later, if their employee tenures average 2.5 years, their workforce will have turned over twice.

Can't expect someone to be "accountable" for promises made by their predecessor's predecessor.

In a post-CBC world, the successor would be asked to renegotiate the predecessor's open/pending agreements or propose replacements.
