Netfabb not free!?

Trying to upload my first design to Pinshape and I went to the “how to” page. Pinshape says to download two free programs, including Netfabb and provides a link to Netfabb. Well - check it out: netfabb is not free anymore. Now what?? For what it’s worth, my Prusa Original i3 MK3 slicer software comes with Netfabb Repair built in. So, my STL files are automatically fixed before I print and save them. Still, the instructions for uploading a new design to Pinshape are obsolete. What do you recommend as a next step? Upload anyway?

same as me
please tell me if you got a information
haha
