take it easyAllowing everyone to enjoy higher rates means cannibalising your own profits".
I would comment on the lexical choice of cannibalising, which is a very shocking, media expression, if related to profits. The subject is also abnormally long, suggesting a speech as context. An option would be to say their instead of your own profits, making it match everyone as a plural, which looks more context-aware.
take it easy"ING Direct now deliberately targets less rate-sensitive customers"
Target as a verb is a classic marketing choice, impressive as well. The emphatic position of now is also telling you that this is corporate propaganda.
Hope this helps, just think hard on different ways to say it and comment on them yourself, just give your opinion, you will easily get a dozen lines
Cheers :)
