That's not a fair comparison. The differences in LP and 1P encryption approaches have been well known for years, and they are fundamentally different.
Now, while 1P encrypted vaults are not brute-forceable the way LP's are, that doesn't mean it's impossible to hack 1P (e.g. malicious code injection in any of their apps or plugins), but I don't like the "everything turns out to be a false promise" broad-brushing when there are real and verifiable differences in how these companies secure your data.
