I disagree. It’s Fairphone’s responsibility to release working phones and keep their customers informed about issues. They have several channels for this, like email, the website, the blog, or this forum. They (as a company) could be more active here (That’s not Monica’s responsibility but the company’s) and actually it would be kind of stupid not to read this forum since it’s a great resource for qualitative user research. I think they should use this forum more.
They could also proactively post to this forum in a sticky post: We have the following audio problems, they are related to software, they show as the following symtoms, please contact support if you are affected. They could also write this as an email to customers who bought the phone and or write a blog post.
