Amen. At my company we tried LastPass, BitWarden and there were revolts from either sales or tech sides of biz... nothing stuck until 1password, since then its been bliss.
The technology hasn't demonstrated the required level of reliability yet. Several companies are getting close, and and early attempts by the companies listed in this thread have paved the way for the FAA to start rolling out the process for scalable compliance. Up until very recently it's all been "approval by waiver/exception", which is very slow, while the FAA figures out along with everyone else what success looks like.
Currently there's approvals in limited areas in the US for testing, and several companies are approved for significant steps towards our shared dream of 5 minute burrito deliveries to our back patios. Nobody has gotten approved for blanket deliveries yet; the safety levels aren't quite there.
Plug: End State Solutions consults and supports companies in developing the conops, safety case, and approval packages. Reach out once your drone company has a design you're ready to freeze for the approval process and we'll help you out. Our team got Insitu and Matternet the first ever commercial UAS type certificates issued by the FAA.
My biggest gripe isn't teams-specific, it's that MS office products still won't support multiple logins. With Google I can be logged into my 4 different work, personal and business accounts simultaneously and switching between the active one is a single button click.
MS won't even support two accounts, so 3 out of 4 times I get invited to a teams meeting I'm in the wrong account, and it's a huge pain to sign out and sign back in; there's no single sign-in (even in Windows!) that works for Outlook, Onedrive, Teams, etc. all at once. Ridiculous.
The "it's a numbers game" thing is a hack to get people out of the trap of not seeing enough new people. You're on the other end of the chart. Commitment is a learnable skill, not something that goes easily once you find the perfect person.
