That's a slight strawman, the same thing applies to owned software. If I own non-subscription software and want to migrate to something newer/better, it won't be easy either. It may be even harder if either or both does not come with support.

Companies ruining their product lines is not really a good argument against subscriptions unless the company has monopoly like power and customers have no choice but to stick with inferior (these exist). If it's a sticky product, it would've been sticky either way owned or subscribed. Password managers are commodities even if it takes effort to move.

Main problem here is bosses want to go with incumbent big dog or has a relationship with sales, sticking the company to products that are subpar or going downhill. If anything subscriptions make it so that there are competitors chasing those dollars while being willing to help you migrate

I was mostly concerned about attachments. The export to CSV worked surprisingly well, even though the CSV doesn't seem to match the spec.

To be fair, I sampled some passwords, not all of them.

For attachments, it took me almost a day, I found an official command line tool called lpass and modified the existing script to do what I needed, then I had to manually re-attach every attachment to the right passwords. A giant pain overall.

Shared passwords is a hard one, they've got you by the gonads there. I moved to Bitwarden and all I did was export my password database as a csv then import it into Bitwarden and it all came across with no issues.
