Real tldr: someone downloaded a fake app and was scamed and here are the author's recommendations:

• Mandate & verify that all published applications using financial and/or cryptocurrency branding are officially published directly by the upstream developers

• Change the store so all initial Snapcraft store name registrations are gated behind human review

• Gate the first month of a new snap uploads behind human review
• Block all interface connection requests behind a human review, including automatically connected ones like network and home
• Fully staff the team doing the above to respond to registration, interface connection and upload requests in a timely fashion
• Send out a clean snap update (as we did in 2018) to all clients that have the scam snaps still installed
• Publishers should have their ’newness’ on the platform highlighted with a ‘New Publisher’ badge
• Snaps that are less than $M (2?) months old should have a ‘New Application’ badge
• Snaps that have fewer than $N (50?) installs should not appear in search results
• The store should make prominent notes to users that newly published snaps and snaps from new publishers should be viewed with extreme caution
• Provide better education to users on the risks of installing finance and cryptocurrency software from the Snap store
• Review and update all wording in graphical and web software store-fronts to ensure users aren’t given a false impression that malware is ‘safe’

Me: What are your recommendations, dear lemmy users? I bet you can come up with much better recommendations

I don't recommend downloading from unofficial distrobution channels without verifying a hash. That said, why doesn't Exodus give Linux users a PPA? Mac and Windows both have auto updates for the Exodus wallet.
