I certainly did!   When I discover a vendor with Linux support, I absolutely send them a note to let them know that their Linux support was the deciding factor in my decision.  Something to the effect of "I was recently looking to purchase a ____________, and became aware of your product ________________, which seemed to suit my requirements.  In the course of my research of your product, I became aware of your (linux driver, linux support, linux forum).  As a Linux user, it is somewhat challenging to purchase QUALITY hardware with Linux support.  Your product certainly fits that description, and I wanted you to know that your support of Linux OS was the deciding factor in YOUR favor.  Kudos, and THANK YOU for that!  Not only will I tell others about your Linux support on my various Linux support and tech forums that I frequent, but I will continue to be a customer for your products as long as you continue to offer Linux support/drivers/etc..."   or something similar, to that effect!  😎

filtering for these tricksters is not easy.  

Did you send them a nice note about the linux drivers?

I have had NO issues whatsoever.  In fact, an older Epson AIO inkjet provided a pretty nice scanner GUI with the linux DEB!  I still prefer gscan2pdf, for the numerous options.  but for a quick scan to PDF or jpg, the Epson GUI was a nice go to!   https://askubuntu.com/questions/1303419/installing-epson-iscan-for-linux   EDIT:  Epson provides Linux drivers for NUMEROUS devices, but states on website they will not provide support for Linux drivers.  I view this as a non-issue, as I'm used to troubleshooting my own issues on non-official support forums; as I suspect many/most Linux users are.  I was just THRILLED to discover linux-specific drivers provided BY the vendor/manufacturer.  I can support that....and I DO!
