In what form does this hounding take? You're painting an ugly portrait of Armstrong, so how does he operate? Honest question - I'm not his No. 1 fan or anything.
In Bassons' case Armstrong spoke to him during a stage of the TDF and the press after the same stage, saying Bassons should leave the sport, as he was known to be clean and criticising doping (In the 1998 Festina affair, several of the guilty riders said in court Bassons was the only clean member of the team). Bassons was hired to write a column daily for L'Equipe in the 1999 tour in which he was mildly critical of drug cheats.
Armstrong has enormous influence and the rest of the peleton starting refusing to speak to Bassons. His team mates started refusing to share prize money with him, and he had to move to a smaller team and gave up cycling the year after
As for Simeoni, I've just cut and pasted the relevant bit from Wiki which is accurate
On the 18th stage of the
2004 edition of the
Tour de France, Simeoni gapped up to a breakaway of six riders that posed no threat to Armstrong's leading position. Nevertheless, Armstrong followed Simeoni, which prompted Armstrong's rival
T-Mobile Team to try to catch the breakaway. This would not only catch Armstrong but also eliminate the stage winning chances of the six riders in the original breakaway. The six riders implored Armstrong to drop back to the
peloton, but Armstrong would not go unless Simeoni went with him and the two riders dropped back to the peloton.
[4] Afterwards, Armstrong made a smug "zip-the-lips" gesture but later said that Simeoni "did not deserve" to win a stage
Of course after this no protour team would hire him and he rode for tiny Italian teams despite being a decent rider (he was Italian road race champion in 2008)
