What's old is new again.
I liked the article and agree with the sentiment. I myself have trouble trusting my data with companies nowadays. The constant cyber attacks, misuse of private data, and the monetisation of user data deeply disturbs me and makes me think a ton before using a new service.
I'm currently building my own budgeting tool for myself and my partner. The pros: all the data is mine, never leaves my own network unless via my home VPN, and I build the features I want. The negatives: I have to build it myself, won't have as much fancy features and nice UI.
This certainly won't be for everyone, and is not viable for most, but there's a not a lot of viable alternatives at the moment.
