Very much so. He kind of got buried under the rug after he abruptly left western culture (and his music career) to become a Muslim.
yes, though that was largely self-imposed I think.
Any musician who doesn't produce and tour gets ignored by the media and the media determine what people buy.
I've one colleague who used to work for the organisation that determines the top-40 chart (the most influential here).
They CLAIM to be based purely on popularity but reality is quite different.
The top 20 spots are decided solely on payment figures. The record company who pays the most gets their artist the #1 spot for the week.
The lower 20 are based on the number of times a record has been performed on radio and TV (and the decisions on what to perform are made largely based on again payment from record companies).
Non-producing artists are unlikely to sell a lot (after all, most potential customers already have the stuff) so don't get exposure in the charts and media. As a result few new customers develop for those artists, causing them ultimately to drop out of view completely except for maybe stations playing oldies and classics.
He's lately re-emerged, but last time he tried to enter the US he was denied by a terrorist watch list. He staunchly denies being a terrorist.
Wouldn't you deny being a terrorist?
Not saying he is one, but just a man's denial of being a criminal doesn't clear that man.
His conversion to Islam and radical statements in the past would have made his name turn up at least to have him flagged as a person with possible sympathies to terrorist groups if not actual membership.
