You are 100% wrong on this. The overstay fee does not make your overstay legal. DR1's lawyer has confirmed this in other threads.
The entire reason for the new minister to say he will enforce the laws is because the overstay fee is a work around
that ignores immigration laws that the PRM wrote in 2004 just before 16 years of PLD rule which ends in about a week.
Here is the link about this work around of paying fees:
Note B under the fees is this:
b. Este pago no supone una prorroga que autorice al nacional extranjero a permanecer en el país.
Translated by Google
b. This payment (of the overstay fee) does not imply an extension that authorizes the foreign national to remain in the country.
(Payment of the overstay fee does not mean your overstay was legal)
