I have used atext[1] and textexpander[2] extensively in the past and both work well, but it's always bothered me that the software reading my keystrokes wasn't open source.
However, it's also the case that the free market seems to now be only in play when it comes to reducing wages, off shoring, and other cost cutting.
The free market isn't at play when it's time for bailouts, subsidies, and government contracts.
Rugged individualism for all, except the wealthy elite.
I'm not sure the person who you replied to has a frustrated / discouraged tone, but that's what I read it as. I share the sentiment and the above is why.
Have you considered how proton mail filters spam? It has to be stored in memory for this to happen before it's encrypted and flushed to the disk.
Unless your emails are encrypted for you on someone else's client before they're sent to your protonmail, in which case protonmail still has all of the metadata (time sent, where it was sent from, length of the message, etc.)
Do you believe proton mail can keep state level actors like Russia, China, and the United States out of their prod infra?
They may be "mostly" subpoena proof as in they can't disclose old emails, but do you trust them to not hand over your data before it's encrypted?
Additionally, if you don't run a full node, you don't know if you own btc.
For those interested in BTC security, the best you can do IMO is glacier protocol (which I'm surprised isn't mentioned in this article) https://glacierprotocol.org/
ColdCard wallets are also an excellent choice, even better when used as a part of a multisig setup with your desktop, more cold cards, or another hardware wallet.
Multisig across multiple hw wallets / computers (2/3 at least) is the best solution to self custody IMO. Single sig is SPOFfy.
This is very good! Congrats!
