Everyone uses their phone differently. I would assume that Samsung did the market research which allowed them to come to this decision.
I myself have always had an sdcard in all my devices but between internal and sdcard memory I never has more than about 120k and half of that was archival stuff that I never accessed so this change has not affected me. Would I still like to have the ability for removable storage, sure, but it did not affect my purchase decision as I always buy devices with maximum internal memory.
There are scores of different phones on the market, buy one that fits your needs and desires.
Galaxy S21 Ultra 512g(VZW), Galaxy Book (original, VZW), Tab S4, Galaxy Watch3 (VZW)
@userRondQU1tdu I understand that you're frustrated with the removal of the microSD port on the new S line phones, however the Community isn't a personal blog. All 39 of the comments on your account are you reiterating the same opinion on several different posts. No one is forcing you to purchase the device. If it's not for you, so be it.

Samsung has really changed. We have had them for years and years. With their service on this phone the S21 I have bought my last one. No charger, no Health reader, no SD card. Top all that off with you telling everyone who is upset to just go out and buy more stuff. I don't want to buy a charger separately. I don't wear watches (will not be starting now). I don't want to carry around an oxygen sensor when my phone should have it. I can no longer give anyone a card with their pictures for that day on it, they have to wait and go to a sight, then download them to their own SD card. Lots of trouble for everyone. <edit>
