Linking to the publisher doesnt limit access in any way   And you may have access and prefer JSTOR but getting from JSTOR to the actual publication if you dont have access isnt straightforward If you link to the abstract at the publisher then everyone can read the access Instead editors have chosen to link to abstracts at paid subscription services instead of the publisher therefore removing access to the abstract and choice of subscription service to the reader  Go ahead and access JSTOR all you want but wikipedia is not the place to promote your access Giving a link to the publisher allows anyone to select their access not yours  So instead of the citation with the abstract the journal name and the author contacts what you give the reader is a link to nothing  Paid subscription services are not necessary to verify information
