However, you find it irritating when people call you selfish when things are catered for you.

Who are these people calling you selfish by the way? Who has said your selfish for not having kids for example.

This frustration with parents seem to come from a sense of guilt? Not that I agree you should feel that way. But all this talk of feeling selfish and being called selfish. I have never felt that way about any friends or family I know without kids. Never even crossed my mind.

If you're truly happy with your lifestyle choice, these things shouldn't bother you at all.

How exactly is everything optimised with families in mind? Ask any parent and I'm sure they will tell you how unoptimised their life is.

Why does a single person with their own expendable income worry so much about being catered for specifically? Your only responsibility is to yourself. Do you look around and bemoan family specific services? It's such an odd thing to care about unless you had a grudge.

Kids aren't a 'lifestyle choice' like deciding to travel. Do I need to go into the reasons why kids are important or who will be paying to keep you alive when your older?

Customers, users… just interchangeable terms to mean the same thing. The whole issue is this particular developer does not build fully featured apps with Apple as they would take too much money out of any generated income (if any). So yeah, this is just about money.

Anecdotal stories of developers watching WWDC videos for info means something? There are millions upon millions of developers who worked and created apps just fine without referring to WWDC videos.

The initial argument was completely different. This person makes companion apps simply because they don't like Apples business practices. Lovely for him I guess.. for most it makes absolutely no sense financially to ignore your customers needs based on a personal preference. Customer will just use a better, fully featured app thats not bound by the developers inflated ego.

Its the most convenient option for anyone who owns an Apple device by far. Its not even an argument, the number of apps and the income generated from customers says it all.

People want fully featured apps, not companion apps. Your personal feelings on the matter aren't relevant to what a customer wants.

Guided meditation helpers are receiving less and less opportunities outside of app stores? What are these shrinking alternative opportunities you talk about?

Likewise, You make it seem that each one of those % values are deducted directly from the $1M/year. Thats not how taxes work.

Never publish anything on Apple's ecosystem as there no alternative... so don't publish at all is what you mean?

All these crazy ideas come from people who don't work in app development, clearly.

Media and companies still pushing the VR hype garbage... its not new, its not 'the future', get over it.

In my hometown, there is a fight between locals and waste operators over excessive burn offs. The validity of air quality readings from the area are being tested in court.

In the past, the Vietnamese government removed IQAir from the App Store and Google Play as citizens became increasingly concerned about the air quality in the capital cities.

You wont learn much if you label everything you don't understand a 'conspiracy theory'. Air quality is not just another weather measurement.

Your certainly not losing your intellectual abilities at 40 or 50, far from it.

40 and 50 year olds will just be moving on to the next stage of their career, using their collected experience to manage and pass on knowledge. Coding requires focus which is difficult to come by generally when you're older and juggling many responsibilities that you've created in your life up to this point like family, finances etc. You certainly don't become dumb.

All the attributes of big tech organisations you described could be applied to many other fields. When you're at the bottom (like a smart 20 year old) and have no control, it can be frustrating. You can rebel against it, play the game, or go out and do your own thing.
