LOL for 2 and a half years!!!

ADS-B is not used by ATC, so airlines do not care about fixing errors or upgrading transponders from Mode-S to ADS-B.

We can hope that this kind of transponder issues will be corrected soon.
This EU document will ground aircraft with broken ADS-B transponders.

Operators shall ensure that a check is performed at least
every two years, and, whenever an anomaly is detected on a
specific aircraft, so that the data items set out in point 3 of Part
A of Annex II, in point 3 of Part B of Annex II and in point 2
of Part C of Annex II, if applicable, are correctly provided at the
output of secondary surveillance radar transponders installed on
board their aircraft. If any of the data items are not correctly
provided then the operator shall investigate the matter before
the next flight is initiated and any rectification necessary shall
be introduced in line with normal maintenance and corrective
procedures for the aircraft and its avionics.
