Try harder. You can run their bridge to expose imap and use any client to export your emails. Also, your info from "years" ago is out of date as they are a small company that has been working on product/features all those years.
Their point was about having to pay to export your data. Afaik Bridge is still to this day only available to paying users. Still, their statement is no longer true since exporting in bulk is permitted for free with the Import-Export app.
