Wasn't aware Handsontable had migrated from an open-source to a purely commercial license, with exceptions, as described in the linked article: https://handsontable.com/blog/articles/2019/3/handsontable-d...
But I'm glad they still allow some free license exceptions for other open-source projects, students, etc and also this part of their announcement:
> That is why we are excited to announce that we will be giving 1% of our monthly net profit back to open source creators.
