Some guy at bitwarden clicks a button wrong on a license drop-down option and all these people crawl out of the woodwork to declare the end of bitwarden being trustworthy. Nothing in the article or the company's statements indicates an actual move away from open source. Big nothingburger
Maybe you want to read the comment by kspearrin in that Github issue again. They are clearly moving away from open source. He explicitly states that they are in the process of moving more code to their proprietary "SDK" library.
