That's not true for professional mirrorless/DSLRs, which on the high end often use other cards like CFast, XQD, or CF. And as mentioned, many readers for those cards also integrate SD readers. The vast majority of people these days just use their phones for cameras, and don't use point-and-shoots or other things with full-size SD cards. So really SD cards cater to just the mid-range camera market, where people use mirrorless/DSLRs but not high-end versions that often use faster cards. I don't think it's a good idea for Apple to make everyone's laptops bulkier so a small minority of people can avoid using a $17 adapter like this: https://www.amazon.com/gp/product/B07NW8RPYN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B07NW8RPYN/ref=ppx_yo_dt_b...
