Why did bill to stem 'foreign influence' trigger protests in Georgia over country's media freedom?

Massive demonstrations have swept through Georgia following the introduction of a controversial law, which opponents argue poses a grave risk to both media autonomy and the nation's European Union accession ambitions. The proposed legislation mandates that media outlets and non-governmental organizations, as well as other non-profits, register as "advocating for the interests of a foreign entity" if they obtain over 20% of their funding from overseas sources.
