It is possible but doesn’t sound all that realistic to me. A truly decentralized app cannot be blocked by dns or endpoints. Thus a country would have to DPI the entire internet which is very resource intensive. And even then the data will be encrypted so you would have to resort to fingerprinting and finding patterns. From an age verification app to automatic data blocking based on deep packet inspection with fingerprinting of the entire internet - that seems quite a leap. Personally I don’t think decentralized apps are next in line to be blocked.
Not really. WordPad supported rtf and things like embedded images. It has been obsoleted by MS.
Notepad doesn’t do rtf, but they did add markdown support. Which I think is an ok feature. The bad part is the application now also includes AI and other unnecessary features and doesn’t feel as snappy and fast as the old one.
