I hate the fact that expressing concern about 787s leads to accusations of being pro-Airbus and anti-Boeing, and this partisanship works both ways. Criticising either maker brings rapid defence from fans of the other.
However, I was already concerned about several aspects of the 787, and this latest seems to add faulty installation and verification processes to its reputation.
It is entirely right to express concern, and does not automatically denote a bias against the maker.
