Ok so providing a worse experience than usual is acceptable to you because there's less money to be made? Even though people still play on those consoles?
Let's just take this as an example: you have 80 hours to finish two jobs in a week, and you cannot work more than 80 hours.
Job A will give you $100 if you complete it, and job B will get you $33 if you complete it. However, for every 1% you don't complete of a particular job, you'll lose 1% of the total.
Both jobs will take you 50 hours, thus you need to do decide: I only have 80 hours to work on these jobs that would take 100 hours to complete.
So what do you do? (Or in this case, what do all businesses -- whether they be video game publishers or grocery stores or tech startups -- do?) You focus on the one that will give you the most money (job A), and then with the time left over you do your best to do what you can for job B.
This is business 101. You will never have enough time to do 100% of whatever you want on any project, so you have to do ROI calculations and prioritize your time.
[edit] to finalize: yes, that by necessity means that some people get left behind, or get a suboptimal experience. But you have to focus on what makes you the most money, and then give best effort to help those that are behind the curve. Why do you think that older phones are no longer supported? Is it because it's impossible to support them? No. It's because the majority of people have moved on from the iPhone 1,2,3, and the amount of time it takes to support them wouldn't be worth the effort you put into doing it.
