As a consumer with limited funds rather than investor I have very few options to Support Jolla with Sailfish.

2 stickers with Jolla logo: deployed
All hardware (tablet / phone) purchased: done
Providing feedback on TJC: ongoing
Try to hype friends into Sailfish: done and failed
Donate to developers of native applications: done.

Become developer: no time and interest and I am of the same opinion as sensible people stated above, what's the use if Saiflish keeps the interface part for telepathy or how is it called closed source? Can't implement SIP in a worthy way, something I would start with on a phone.

Again, I would like to purchase the software Sailfish in a form originally intended by the Jolla crew in their idealistic free from Nokia Elop days.
Here I have purchased an alternative ROM for my Kindle Fire. Purchase, install , play. Tired of new OS? Run uninstaller to invert operation and get back to original OS.

An "old" phone loaded with an officially supported 100 Euro Sailfish license would make very original Xmas presents compared to latest Galaxy S.


Another way I would support Jolla is through their indiegogo campaigns. If they would search for support to implement the top 10 jolla together most voted or requested items.
