If you change your license to exclude this particular use, it's no longer Open Source (no restrictions on how it's used).

If you change your license to forbid removing the license, then there's a good chance that it doesn't hold any legal power. Reason being that machine processing is allowed by copyright laws.

But almost all licenses already do that, for example the MIT license says:

> The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Therefore, changing the license is not going to improve matters at all. It's already forbidden, yet we are where we are.
