well first mineplex is an OFFICIAL minecraft partner, second it took 40 people(me included) 3 months to code 45,000 command blocks to run the server. second it cost roughly $1500 USD to get the host that can run that kind of thing. third there are no plugins because "minecraft" is coded in C++ as opposed to "minecraft: Java Edition" which is coded in java. that is why we can't get one. Minplex also gets about 36000 players a day on the java edition alone. meep gets an average high of 30.
