The thing with the artist not owing anything to fans argument.
Some are saying Madonna, being an artist & deserving such respect & not "owing anything to fans", but she couldn't be an artist in the way she has been without fans buying her records, concert tickets, & by all of us responding to all of her artistic efforts, talents & hard work with our support. Those hundreds of millions of dollars she has in the bank & all the power she holds is all from us directly or indirectly through our various means of support for her.
She DOES say thank you all the time to her fans, not on every social media post or public appearance, if she did, that'd be boring & lose meaning. Fans who demand & expect her to make the music that THEY want her to make in the way they want her to make it, on the schedule they want her to make it, are not respecting the artist. If she has made music that you have appreciated, then appreciate the fact that she IS AN ARTIST and let her make the musical statement SHE wants to make. She does respond by giving fans what they want with many albums, but with some albums, those are the albums SHE wanted to make. Sometimes the receptions are better than others. Whatever. It just adds to the texture of her legacy. American Life was not well-received by fans for the most part, yet a lot of newer, younger M fans state that album is their favorite now, so time tells a different story with the "flops", but that's another discussion.
Also, the fact that she puts her money toward projects like schools in Malawi, etc, isn't a thank you so much as a putting the money she makes toward shining light in the darker places of the world & lifting people up. I know she didn't use all of her own money but she definitely used some and brought in money from other sources, using her hard-earned power for good.
Another point: yes, I've spent ALOT of money on Madonna in my life, but what I've gotten back from her & her songs, work, energy, wisdom, is my life has been made better. Finding strength through her as a gay teen in the 90's when I felt so marginalized & outcast in many ways by not fitting in to the world & expectations my family & society had for me. SHE empowered me through all of it & I LOVE HER FOR IT. Make the music you want to make & I'm here to accept it & enjoy it however I may.
