I don’t think this is true at all. What do you mean by “general bricks”? If anything there is more brick-built stuff nowadays.
For example the Creator 3-in-1 Castle (which I got for my son for Christmas) is pretty similar to castle sets I had as a child but basically way better and with brick built horses rather than large mould ones
