its been almost 3 months since Playstation 5 launched why isn't sony making anymore?

have you thought they have supply problem , there in great demand , or are you to dumb to think of that troll .

They are but when they are in stock, within 30 minutes, there all gone. It's just high demand and low supply.

They are.  You’re just not working hard enough to get one. I wanted one so I worked hard to get one. I signed up for notifications. I’ll refresh websites when I’m not busy. Eventually I was able to get one. 

Sony has been slowly releasing their stocks. You just need to be signed in with your PSN account. Sucks if you have an iPhone because it doesn’t seem to work if you use iOS. I can never log in to my PSN on my iPhone.  

They are still being manufactured, but they're just selling as fast as they can make them (or are choosing to make them). It takes some good luck and timing to be able to find one.

They are

yet, they are purposefully restricting the amount produced

They are
but they are intentionally limiting the quantity manufactured

Basically
they don't want to get in a situation
where they're stuck with warehouses full of PS5s that they can't sell.

SO, they limit production
which means they can keep prices up (supply and demand)
and not risk being stuck with a large inventory that
whether for reasons of shipping restrictions (Corona)
or for technical reasons (something wrong with the units themselves)
they would not be able to sell.

They have good reason for caution. Sales in Japan itself have been surprisingly poor.
