What the article doesn't mention is that it was just 3 weeks ago that the police declared Uber/Taxify illegal in Estonia, after a 9 month investigation of one Uber driver. [1] The government's idea of legalizing it was already in progress then behind the scenes, and they vowed to increase their efforts after the police's statement. This is that moving forward. Also, in a rather uncommon twist, although the police spent 9 months investigating this Uber driver and found them guilty, they decided to not apply any punishment, because the driver "wasn't aware of the law".
