I wonder how the recent ruling of the Bavarian state court regarding Google Fonts and GDPR affect Storj and this proposal?

Not really. According to the ruling, this is specifically targetting Google for being US based, known for data mining and its broad reach which means that the impact when Google collects this data is much more severe compared to another small 3rd party website.
Thus a payment of damages might be justified in such a case concerning Google but not necassarily for embedding content from other websites.
