Is it appropriate for a Muslim preacher to showcase luxury items publicly?

Assalamu alaikum. I'm curious about whether it's appropriate for a Muslim preacher or teacher to post pictures of expensive branded items on a public social media account. I came across a Muslim man who presents himself as a preacher and educator (not naming him). He holds a podcast, speaks at colleges and universities about Islamic morals, and his audience is mostly middle‑to‑upper class youth who can afford those institutions. His talks cover issues like LGBTQ, transgender topics, addiction, party and drug culture, free mixing and other modern moral problems that tend to affect wealthier young people. I tried to raise a concern with some of his followers: I felt that a public preacher showing off a luxury ride and hobbies that only well‑off people can enjoy might hurt those who are struggling financially, causing resentment or bitterness. Given the hard economy, many can’t afford such high‑end items, and I thought he should show sensitivity toward the less fortunate. Instead, people accused me of jealousy and low self‑esteem, and said he was simply connecting with his audience of wealthier youth. They pointed out he bought it with halal income and that a Muslim preacher can have money, hobbies, and enjoy wealth. I did say I had no problem with his private life, but felt public displays can be interpreted in different ways. Most replies were a full defense: that appearances matter to reach certain people, that he’s breaking the stereotype of a simple poor preacher, and that showing success helps attract and influence his audience. It made me wonder if they would react the same way if a female preacher built her whole channel and style around an expensive designer brand or openly flaunted luxury items. I suspect she would be called immodest or attention‑seeking, and judged more harshly. I can’t understand how strongly people will defend their favourite Muslim influencer and ignore criticism. The double standards felt striking to me. What do others think? Is it better for public religious figures to be more mindful about displaying wealth, especially when addressing mixed economic audiences? JazākAllāhu khayr for any perspectives.
