they made a blog post, but what information was passed? And actually in this same post they said they'll post info "soon". So they made a post with no info, saying that info will follow and nothing.
Btw when they said they'll opensource UI parts, they made a huge noise about it at conferences they attended and talked about FOSS, but when they changed their mind, they just did not update anyone, and when people started to ask, only after disputes, fights and rants, they told that they would,... maybe.... someday...
This is exactly the example of promising anything before product and disappearing straight after they did not keep promise. And it's ok if things changed and there is reason for that, but they do not need to wait till sh*t hits fans to communicate and explain.
Developing behind closed doors and not sharing info is far from transparency and opensource they talk about. Just look at facebook and google and even microsoft, they have a lot of FOSS projects they contribute and even meetups and everything which would make you think they care about FOSS or you, but we all know what they care about and hwo they make their decisions, Jolla is no different at all.
