The CDMA processors which Apple and other premium handset makers need (not for all of their phones, but for those that are to work on CDMA networks) aren't made by anyone else.
On the contrary, what's happened is that most companies have stopped making/using
standalone broadband processors, and instead now only make chipsets with that part
integrated them into their application processor.
For example, Samsung, MediaTek, Huawei, and Via Technologies all make CDMA capable chipsets. They need them for the US and China markets.
But the CDMA processor section is now incorporated into a CPU design that also includes GSM, WCDMA, SCTDMA, LTE, etc.
So Intel can't build those kind of processors (CDMA multi-mode) in part because Qualcomm, in violation of its agreements, in effect won't let them.
As noted above, Qualcomm certainly does allow it.
As for Intel, they bought into Via Telecom in 2015 explicitly to get access to its CDMA patent licenses. So reportedly Intel could (and might yet) build CDMA into one of its coming modems. They're just starting out slowly with the basics.
The rest of your speculation is based on the above false presumptions.
The FTC claims that these are not standard industry practices - indeed, that Qualcomm is unique in its licensing demands - and in violation of FRAND terms.
I think what's confusing is that there can be a difference between patents for
making chips, and patents for
using those chips for CDMA (or any other protocol).
As noted above, several companies are making CDMA capable chipsets. Also, Qualcomm has licenses with close to two hundred companies for the code to USE those chips in actual CDMA situations. But NOT EVERYONE wants to use the CDMA capabilities. (Or the GSM capabilities, if you're Sprint or Verizon.)
Think of it like the difference between licensing the ability to make an Intel CPU chip, versus also licensing an OS to use on that CPU. You don't usually pay the chipset maker for the OS. Likewise, you might want to buy a modem chipset that can do LTE, but you don't need the CDMA or GSM sections and therefore don't want to pay for those licenses for no reason.
That's why phone makers usually have to buy the specific usage licenses
separately from Qualcomm. You can get the chipset from several places, but you only have to pay Qualcomm for any particular IP you use along with that chipset.
Qualcomm likes to keep it separate partly because it makes it easier for them to account for its IP users. It makes more sense than asking chipset makers to collect specific royalties from each of its chipset buyers (assuming chip makers would even
want to take on that responsibility).
