Yes, but just like pretty much every other gaming peripheral brand. SteelSeries, Corsair, Logitech, Asus, Glorious PC Gaming Race (that's actually a brand
), Roccat, Zowie and etc are in this for making profit margin and likely a huge profit margin. I wouldn't really exclude Razer, it's just that they were the OGs of overcharging for no good reason.
And then there is something like Cooler Master CM110. RGB, adjustable DPI in 5 steps, 1000 Hz polling rate, optical sensor (PixArt PWM3050) for just 22 EUR (26 USD). It's essentially SS Rival 3 clone, slightly worse (DPI adjustment steps), but at steal prices. That's really all what gamer needs, some might need more (more granular DPI adjustment and programmable DPI button) and there's similar, but better SS Rival 3 for them, which retails at 32 EUR or 40 USD. You can only dislike it, if you don't like its shape. Otherwise, those two mouses are awesome at their budgets and still have acceptable value for gamers. Beyond those two, it's near impossible to justify anything more expensive.
