To a degree, our current company exists because Yoast SEO made enough bad decisions that people switched to our WordPress SEO plugin. My friend wrote it only because he disliked Yoast and as every programer, he thought "I can code this in a weekend and it will work better". It was never ment to become a project.

Anyway Yoast eventually made a big enough mistake and 5 years later my programmer friend is working on this full time. I am the only other guy working with him.

Transport of data was at that time trivial.
