Copyright is regularly abused by large corporations in the pursuit of more money. Previously it was primarily used as a cudgel against individuals (against piracy, parody, and fair use). But now that their own rules are inconvenient to them they ignore its existence in pursuit of further profits.
Copyright to protect large companies? Fuck that.
Copyright to protect individuals from having their work appropriated? Yes please.
Copyright is already abused against individuals. Corporations already have these powers. What people want is the ability for these powers currently only available to the corporations to be available to the public. I've not seen anyone arguing for corporations to be granted more.
Trying to support individuals enforcing copyright against corps isn't going to change the fact that corporations alrwady have these rights, it's just trying to get corps to play by the same rules they apply to us.
Plus, any of the critically needed changes to copyright law would be fucking useless as long as we allow corporations to ignore what already exists for the sake of convenience.
Completely discarding concepts and arguments based only on the fact that they are associated with "the enemy" is dumb as hell. Likewise, "owners of intellectual property" != "only companies". "Owners of intellectual property" covers anyone who takes photos, writes text, makes art, or makes original "content".
Unfortunately LastPass had some issues over the past years with hacking where encrypted vaults were stolen. Between myself and my friends in tech, I know of a few conpanies that ditched it after that.
For individual/personal use, I'd reccomend KeePass (whatever fork of it is up to date and maintained lately) and using somethung like syncthing to sync it across devices. That may not be super user friendly for non-technical users though, and I'm not sure how well it works with iPhones.
