If owning shares means having an, admittedly small when it comes to a firm the size of Boeing, part in the decision making process and a financial stake in the company, then yes, in principle. Shares aren't a vacuum-sealed number-go-up game, taking a share means an interest in supporting a company via investment or a desire to be involved in the decisions (which usually requires a substantial investment as a proof of stake).

It gets a bit murkier when it's all mashed and derived and packaged to death which results in things like the Church of England accidentally (or at least they divested when it was pointed out) having shares in things that it doesn't share philosophies with such as oil companies.
