Your questions:
1- Why should tabs return (you asserted them as weak)? If it costs them users and paid subscribers, that matters some, at least. It is not that I do not like the alternative, but rather that I am moving to an alternative and not using EN nearly as much as I did previously (estimated 25% of the past usage).
2- "Why should those who are not accustomed to it start to use it in the future? Where is the benefit (over independent windows)?" I assume you mean using tabs if they returned. First, it gives users multiple ways to interact and use the content of EN. Like Mel10 stated, in a day where open source is high and software is built to customize for the user experience, this seems like a no-brainer. For those who should start using tabs in EN, flip the argument of the many that state to use tabs with EN in a browser. Do you use browser tabs? What percentage of people do? Do they consider those tabs useful? Did they find ways to use the internet before tabs and only windows? Sure, but most people I know use tabs in their browsers because it allows quick access to many sites without getting lost in the feel of 95 MS Windows and cluttering up their screen. Tabs to the browser were considered an upgrade, as well as organizational and cleaner screens. The same is true for EN, the VERY SAME.
If you want to tell those of us who want the return of tabs to EN that we are wrong, stop using tabs in your browser.
3- For a bonus to your 'Tada" I am not sure of your facts. First, Windows is around 69% of computer users, and Mac is 21%. Also, your 'facts' do not speak of a % of paid users vs. free users. Your facts are right. In the end, I get it, money talks. But I'd like to know why browsers are adding or advancing their tab features, and you and others are arguing that tabs have limited to zero value other than our refusal to change. Chrome in 2020 did not do away with tabs but added and enhanced tabs by creating groupings of tabs. MS Edge did the same in 2021. Simply, while EN was removing a loved feature from the Mac OS user, they could have been adding it to Microsoft users like browsers.
I hope you were listening!
