Nobody lowered the time Poles or Russians spend learning their own languages in Russian or Polish schools, but time spent on Lithuanian language lessons ofc increased ( and is now about the same as for Polish and Russian ones ). That was done because previously most people who attended these kinds of gymnassiums had an insufficient level of Lithuanian and had a harder time getting a well-paid job, thus increasing income inequality between ethnicities.

Lithuanizing names is mainly done so that officials can spell them and write them properly ( because ofc only a minority of people can correctly spell or write names in Polish ), but most parties today agree that allowing people to write their names in original language must be allowed, as long as a Lithuanized name is also used on official documents.

Only bilingual markers and street signs were removed, nobody removes Polish or Russian store signs and that is once again for the sake of simplicity, as is the case with passports, most parties today agree that bilingual official signs in majority Polish areas could be used.

Lithuanization happens no matter what. Media is Lithuanian, official organizations are Lithuanian. If you really think that letting minorities go around refusing to learn the official language is a good thing then you must be slightly dumb.

And this Polish party is a pro-Russian government party. It has done literally nothing about passport or bilingual sign issues. The only thing it was succesful in was marching in Vilnius shouting "Wilno nasze" and saying things like "Its the lithuanians that need to assimilate ( in majority Polish areas )". If anyone supports Polish party it is either because they are still salty about dissolution of the USSR or because of their shady way of getting votes.
