Automated Testing and script writing capabilities

Read the text about testcomplete on the automatedqa Website:

Test Complete is an automatic test Manager, with project level support for the full range of internal and UI testing. Designed for developers and testers.

Testcomplete is an automated test management tool that fully supports the interface layer andCodeLayer test. Designed for software developers and testers.

Recall that some people on the Forum said that TC is difficult to use, and many qtp users do not have it. I want to understand this passage. With its ultra-low price, TC supports a wide range of application types and control objects, and supports unit testing and interface layer testing, it is intended for a developer or an automated testing engineer instead of a novice tester or a person who does not understand the script code.

Coincidentally, this is related to the slogans of the advancedqtp Website:

'Coz we're programmers-not users

I have always thought that it is unrealistic to allow all testers to participate in automated testing and to involve those without any foundation for automated testing Script Development!
