For those without an institutional budget, there are excellent open-source tools for molecular modeling and simulation:
Because the value of the software is immense, Schrödinger employs various anti-tamper measures. Code obfuscation is standard, making the compiled binary difficult for humans to read. Furthermore, modern versions often integrate checks that "phone home" or validate the integrity of the binary itself, ensuring that the mathematical engines (the proprietary algorithms that calculate binding energies) have not been modified.
