Kate Pickert at Time Magazine makes an important point about what the post-Supreme Court ruling for Hobby Lobby employees means:
Women who work for Hobby Lobby had, and still have, full insurance coverage for most types of birth control
Although the Supreme Court ruling opens the door for closely held companies to make other future objections based on religious beliefs, Hobby Lobby's individual position is less extreme than many believe. The company objects to paying for morning-after pills and inter-uterine devices, but freely provides insurance that covers tubal ligation, birth control pills, condoms, diaphragms and contraception delivered via a patch or ring inserted into the cervix. More than 80% of all contraception users in the U.S. rely on these methods.
The point of Obamacare's contraceptive mandate was to increase access not just to birth control pills or diaphragms, but also extend coverage to all types of FDA-approved contraceptives. Insurance coverage can be especially important for women making a financial decision about whether to use an IUD (which is both the most effective but has the highest upfront costs, sometimes upwards of $500). Hobby Lobby is extremely unlikely to cover IUDs given the objections it voiced in court, but to say it doesn't cover any birth control is not the case.
