Note: back in the iPod days, iTunes did serve as a music store for the iPod, but you could buy MP3 files from other providers as well, and transfer them to the iPod via iTunes. This whole process didn't "cost" the provider or user any extra.
Now, it's true that iTunes did get significant traction because of convenience for users of iPods, however there were definitely options for other music distributors. In fact, back in those days, I tended to still buy CDs because they were DRM-free and similarly priced, and I could rip the songs at my selected quality settings to transfer to my iPod.
Note: this is a bit cherry-picking out of context, which I'll admit sometimes happens in Christian circles as well. But I think understanding the context and culture of the time can make things a bit more clear. Yes, the culture of the time had a different handling of gender roles, and some of that persists in other cultures around the world to this day. These were letters written to the Christians in the churches of the day. Likely the content would be written slightly differently if it were written to a church in the modern day USA.
For example: Ephesians 6 goes on from what you clipped:
25 For husbands, this means love your wives, just as Christ loved the church. He gave up his life for her 26 to make her holy and clean, washed by the cleansing of God’s word. 27 He did this to present her to himself as a glorious church without a spot or wrinkle or any other blemish. Instead, she will be holy and without fault. 28 In the same way, husbands ought to love their wives as they love their own bodies. For a man who loves his wife actually shows love for himself. 29 No one hates his own body but feeds and cares for it, just as Christ cares for the church. 30 And we are members of his body.
This seems to me to indicate that husbands should be self-sacrificing and putting their wives' needs above their own. All the submission indicated here is similar to the way that Christ (the Son) submits to God the Father. These would have been very strong and shocking words in that culture, that normally would have allowed for husbands to have complete "rule" over their wives, and instead is urging husbands to self-sacrifice for their wives. So if anything, it would have been improving the standing of women rather than "keeping them down."
If you're married, have you ever willingly given up on your own desires, instead following your spouse's needs/wants? Have they ever done the same for you? This seems to be what this passage is encouraging.
