How is it deceptive? Are they bumping version numbers? Are they packaging new releases?
Edit: before I'm accused of not reading the article, I did, but I did not look at the actual OpenOffice download page. The current release, dated April 2023, includes the following, which seems substantially more than "whitespace cleanup" as TFA author claims, but seems quite in line with software that is being maintained but not actively developed:
Other Improvements/Enhancements
Writer: Dialog "Frame" in Writer / automatic size / changing shortcut keys (German)

Calc: Use the existing icon for "Remove Filter" in toolbar and menu
