Yipp, I don't like it too, but most people stick to their brand (and usually Canon knows best how the market works).
Brand loyalty has never made much sense to me, but it does seem to be an affliction that many people suffer from.
I have the impression that Sony is more popular for younger users, so that Canon might get problems in the future.
I'm in my 50s and have used most major mounts at one time or another over the last 30 years, and some minor ones too. These days it's Sony but when Panasonic finally gets their AF issues resolved (right now they have about A7III levels of AF, as in 2018-level tech) I would seriously consider buying an L mount camera. Their IBIS is unmatched for video, it really is impressive.
But I also see that the new(er) 3rd party lenses - from China - are relatively good for their low price, but they can only offer MF lenses for the RF mount or AF for the EF mount with adapter. If these 3rd party lenses would be available with AF for the RF mount, that would probably hurt Canons financial results a bit (and they still recover from the smartphone competition).
Canon has always hated 3rd party glass. Back in the days when Sigma and Tamron used to reverse engineer mount protocols, Canon would break compatibility with every new camera release. Canon's shenanigans (and to a lesser extent Nikon's) are why Sigma went down the road of releasing a USB dock and having lens firmware updates. Prior to that a lens with broken compatibility would have to be sent back to Sigma for a chip swap. Very annoying, and of course eventually lenses would no longer be supported and would just stop working on most cameras.
Well, the lack of lenses for the RF mount is a severe issue!
Over time Canon will release more RF glass, but the Canon tax will always be high and the selection will never be as good as it would be with 3rd party glass in the mix. Lenses like the Tamron 35-150/2-2.8. Amazing lens. Will Canon release something like that? Probably not. Or the Sigma 135/1.4 or 200/2. Both are good astro lenses that will never come to RF. New Sigma 105mm should come sometime soonish and since they already have a 135/1.4 I personally think they might do something crazy and bring out a 105/1.2. Of course that will never come to RF either. Then there are lenses like the Sigma 300-600/4 or the almost unbelievably small 500/5.6. Or the all in one 20-200 lens which is surprisingly good for a superzoom. None of that will come to RF either.
And of course that does not touch what Viltrox is doing which is awesome itself. Their PRO and LAB glass is really top tier. Their first EVO lens (85/2) punches so far above it's price class that it feels almost criminal. Then the tiny AIR series like the 14/4 that I paid only $159 for. It's no astro lens, but it is very good wide open and lets me play with a crazy-wide lens for what is essentially pocket money.
Plus their are other Chinese companies like TT Artisans that have very cool little lenses like their 75/2 that comes on sale for $160 at times. I've taken some incredible photos with that lens. $160!
And for cool macro, T/S (at half the price of Canon or less!), and STF glass there is Laowa. I own several of their lenses too. Oh, and we shouldn't forget the Laowa AF 10/2.8 or AF 12/2.8 primes, either, nor their recent AF 200/2 release. A 200/2 for under $2k?? And that's not even a sale price! Really wild.
And China is only just getting started. This year we will start to see AF zoom lenses from them, and camera bodies (probably L mount) are not all that far behind.
a 105/1.2 might be the thing that pushes me over to the dark side, together with the 135/1.4, the 200/2 and the near-mythical 35/1.2. This would be a disaster for my wallet, especially since all the money I have donated to Hasselblad
