Vendors are designed to own you and ownership can have different forms. Slack.app that doesn't let you easily extract code snippets from a thread - owns you. Jira that forces you to use their imbecilic, quirky wysiwyg owns you. Note taking app that keeps the data in their db and not your files - ain't your friend. The friction is the ownership. When extraction of text requires effort, the tool has leverage over you. It's a subtler form than data lock-in - behavioral lock-in. You adapt your workflow to what the tool makes easy, and gradually the tool's affordances shape what you even think to do. Information gets buried in threads, search is mediocre, export is hostile. The "solution" they offer is to stay there longer - search in Slack, link to Slack, screenshare in Slack, summarize with AI in Slack, don't ever leave Slack. The tool becomes the answer to the problems the tool creates. It doesn't become "invisible" like the article says, you just don't realize that you're "lost" yourself in it.
Most popular editors and IDEs don't give you direct leverage over plain text either, at least not without the effort from your side. Shortcuts, popups, UI elements in the IDE at best are local drivers - you can't easily grab a thing from the outside and feed it to your LLM context in the middle of a task, or insert within a comment in the code - you have to switch, copy, paste, deal with format inconsistencies, manual conversion, etc. Then we keep bargaining what method is the best, fastest and most convenient - using the mouse or keeping the fingers on the home row, modality or complex shortcuts. All for the sake of the problem that's artificially enforced on your workflows.
Terminal-heavy users eventually start appreciating the leverage Unix philosophy grants them over text, but that's still contained within locality, they still have to constantly jump around, while eventually figuring out ways for automating some aspects of it.
Anyway, this should be a little more of a deeper discussion than a forum comment. Point is - do not give in to the status quo. Liberate your text - deal with it on your terms. Get annoyed whenever you need to switch back and forth just for the sake of finding the piece you need and moving it around - it should be instantaneous and instinctual. Like boxers moving on a ring and casually throwing punches. Long time Vim and Emacs users "get it", even though often don't follow true - some things never become gratifying instincts. Sometimes, even the opposite forms - redundant muscle memories.
