The time frame is incorrect - not truth. A lie.
The first sentence of the article says it was effectively banned BY ROME. Also not truth, also a blatant lie. It never was. Produce your document which says so, because the Encyclial accompanying the promulgation of the NO certainly says no such thing -
papalencyclicals.net/Paul06/p6missal.htm and I don’t have time to do an indepth search for other documents.
As for those ‘private Masses’, my understanding is that the restriction simply meant they couldn’t be publicly advertised in bulletins or newspapers and such like NO Masses were.
Doesn’t mean lay people who were told or otherwise found out where they were happening, on a private basis, couldn’t attend them, nor that those lay people couldn’t tell others about 'em too. I’ve heard numerous stories of lay people who did just that.
Not to mention that numerous religious institutions (monasteries and convents) held them, held them regularly, and permitted lay people to come along too, they didn’t shut the doors on 'em. St Padre Pio, for one concrete example - he was allowed to continue to say the TLM, said it at the same time every day and in the same place as he always had, EVERYONE knew and could attend if they so desired.
Their restriction for ‘private’ use, as far as I am aware, doesn’t mean, as you seem to be implying, that laity couldn’t attend them, they most certainly could. I’d like to see you demonstrate the contrary.
