There's a lot to unpack here.
You're unwilling to hear out others on why certain sync methods can be slower, so I'm unwilling to answer to that.
You yourself disprove manipulation by begging for the WebDAV sync guide that already exists. It shares instructions with the Nextcloud sync guide that also already exists. Before you ask, setup instructions for both services are easily found elsewhere on the Internet.
As for Google Drive support:
Developers, like users, are allowed to point out issues without offering solutions. Community members also deserve the respect to not be falsely accused of:
- Manipulation
- Conspiracy
- Hypothetical and ambiguous responses
- Writing a lot and saying nothing
- Critiquing others' answers for not answering unrelated questions, and
- Other outlandish claims that apply more to your walls of text than theirs.
Please explain, in detail, the rationale of an open source software developer throttling bandwidth for sync options that a large portion of their program's users use, let alone the implementation.
Calling Laurent - the main developer of the program that you trust to edit and store your eleven thousand notes and counting in - "incompetent" is not a solution.
