Infura a link between us and the Blockchain network. How can I trust with is as a third party?

Hi infura!
and I wonder if the possibility to modify the data passing by infura? please explain for me !

Infura does not modify responses and data is equivalent to that being served out of a geth or parity node. We use TLS to secure your application’s end-to-end communications with our infrastructure.

Transactions especially can not be modified because they are signed prior to being transmitted through Infura.
