I don't want you to do anything.I'm pretty confident about this, but if you want me to be semantically correct as if I'm writing a dissertation, sure. I don't proofread everything I write and I'm not immune to all logical/semantical errors. There's always room to re-think something, especially when dealing with incomplete information.
If you say, 'lots of companies definitely ...' then a reader is left to wonder whether you are citing a source, or offering an opinion. That reader may then ask you to cite your source. You can simply say, 'I got nothing.' Or 'me.' Or etc.
OTOH, if you say, 'I doubt many companies ...' then a reader clearly understands you are offering an opinion.
Talk anyway you like.
